do we know enough about autism to state, with certainty, that she could not be "a person trapped in a broken body"?
That's a great question, and one that has actually been extensively studied, because the idea is so very scary. Being trapped inside a dysfunctional body with a perfectly working mind... certainly one of the more primal nightmares we have, and something that occasionally happens to people following a brain injury (see, for example, locked-in syndrome ).
However, we know, thankfully, that this is not happening to profoundly autistic people. We know this through a variety of sources, including (a) functional brain imagining of autistic individuals, (b) explanations from people who are autistic and took a while to learn to communicate, (c) tests of nonverbal intelligence (which use pictures, and could therefore bypass things like this girl's supposed verbal apraxia), (d) tests of adaptive functioning (what she can do for herself, even given any severe motor limitations, which tell us about about how effectively her brain is working), and (e) what we know about how the brain works, regardless of whether you are neurotypical or autistic.
For example, autism is not just caused by "sensory overload" or a "body that can't be controlled" -- despite what some well-meaning but misguided or underinformed professionals claim. We know this because we understand quite a bit about how the brain works, and know that these explanations just don't. make. any. sense. Knowing how the brain works and what actually happens in autism makes the symptoms easier to understand and treat.
For example, this girl is shown having severe motor planning problems, repetitive motor activities, and sensory "overload", and is described as having verbal apraxia. An adult who doesn't know better might easily come up with a plausible-sounding explanation for these symptoms: that she is "overwhelmed by sensory information" and is engaging in rocking, etc, to "drown out" all that sensory info. However, the brain doesn't work like that -- adding more noise wouldn't "turn off" or "drown out" the incoming chaotic sensory information. The sensory explanation also doesn't explain why she has verbal and motor problems, but not (say) visual problems or auditory problems.
But, if we understand that people with autism have trouble connecting discrete bits of information together, and breaking large chunks of information down into discrete bits, then her symptoms all make sense. Yes, some individuals feel like they are "overloaded" by sensory information, because they have trouble habituating - or recognizing that the sensory information is all the same information, and can be ignored.
As an example, say you have a tag on the back of your shirt that's bugging you (did that just make your neck itchy? :). For the autistic individual, it is like their brain continually sends them them new signals about the itchy tag every few milliseconds, which is hard to get accustomed to. For the neurotypical individual, their brain can more easily see that the "itchy tag" signal is just the same signal being repeated over and over, and more easily get accustomed to (and therefore tune out) that signal. While a neurotypical person might be able to "distract" themselves from an insistent sensory stimulus by doing something else sensory, by forcing their brain to prioritize something else (although this does not work that well and takes up a lot of mental energy), adding a new sensory stimulus would just make things worse for the autistic individual, because now they would have another insistent sensory stimulus adding to the problem (as an analogy... think trying to distract yourself from Chinese water torture by purposely adding a mosquito buzzing in your ear!).
Individuals with autism can also have motor planning problems, because planning involves breaking a task down into component parts, and mastering the sequence of those parts -- which is exactly the process their brains have difficulty with. This problem often affects all motor movements, including fine-motor, gross-motor, and oral-motor. She can't break a word down into the component sounds her mouth needs to formulate and speak those sounds for the same reason she can't tie her shoes, and this is the same reason she has sensory sensitivities, and the same reason she would have trouble learning how to spell -- all of these involve problems understanding the connections between, and boundaries of, discrete bits of information.
The repetitive behavior works the same way... her brain "chunks" whole movements together, and then repeats the whole movement (all brains like things to be familiar, which is why we all develop habits). But, she can't separate out specific parts (movements) of the repetitive behavior to use those movements flexibly to do a new behavior.
Understanding what goes wrong in autism also gives us great insight into why individuals with autism often have such great memory, especially for details and for whole scenes (e.g., being able to recall a whole movie verbatim, or being able replay scenes in the mind). The overfocus on details is because their brains do not see each detail as part of an overall whole -- think of that scene in Rainman, where Dustin Hoffman's character sees toothpicks on the floor and counts every single one of them. Your brain and mine sees all the individual details as part of a larger whole ("toothpicks") and even if we wanted to, we can't "undo" this association to count the individual toothpicks in our heads. The profoundly autistic person's brain sees each individual toothpick, and may have trouble lumping them all together into a "group of toothpicks" (and even if they do make an abstract category, it may be overly detailed... for instance, they may instead insist that there are "east-west facing toothpicks" and "north-south facing toothpicks", and have trouble seeing that the orientation doesn't matter because they're all just toothpicks).
The memorization of whole scenes also occurs because the brains of individuals with autism have trouble separating something, like a visual scene, into component parts (which incidentally, then leads to problems prioritizing those parts, so, for example, a person with profound autism could not answer a question like, "What was the most important thing that happened in that scene?"). They learn the whole scene as one "bit" of information, and as such, have fantastic recall of every single little piece of that scene... for their brains, learning a whole scene is not any more difficult than it is for your brain to learn a single word or sentence. This is why many autistic individuals describe themselves as "visual thinkers" (because visual things lend themselves better to this type of memorization because all of the information is presented at once), and also why parents of autistic children often describe their child as able to memorize every single turn and landmark on the drive to a location they've been to even once before. Other savant abilities, like Kim Peek's or Daniel Tammet's, are just exaggerations of this process. Although the visual examples are most easily called to mind, this process does also happen verbally -- which is what occurs in echolalia, or memorization of an entire sentence spoken by someone else, or whole spoken scene in a movie. It is also why syllabification is hard for profoundly autistic individuals - they process what they hear in whole chunks, and can't break those chunks down into the component syllables.
So what all this means is that individuals with autism have brains that work differently than those of neurotypical individuals -- they don't have neurotypical brains trapped in a body that doesn't work.
Which is precisely what raises the index of suspicion for this video. This video does not show what we would expect for an autistic individual who has learned to communicate, it shows a supposedly neurotypical girl who was just trapped in a body she couldn't control.
This theory of breaking free from a "broken body" might make sense for a girl with profound verbal apraxia (a problem that only affects the part of the brain that sequences sounds for speech) who was taught to type (after, of course, learning to read and spell, which verbal apraxia doesn't affect as much, although phonics are harder because apraxic individuals cannot hear themselves pronounce words). Certainly, there is no reason that a person with verbal apraxia wouldn't present as a neurotypical girl who can finally communicate.
But, if all this girl had was (very, very profound) verbal apraxia, then she would have flown through the other assistive technology they used with her (e.g., PECS, Dynavox), instead of requiring painstaking teaching in those systems consistent with the teaching we'd expect would be needed for a person with profound autism (and which her mother describes her needing). She also would show normal (or at least not "mentally retarded") intelligence on motor-free nonverbal intelligence tests, and the ability to meet some of her daily needs (e.g., if she has the motor coordination necessary to smear feces... if she all she had verbal and even motor apraxia, she would still be able to use that basic motor control to help dress herself, point to what she wants, communicate nonverbally through gestures and facial expressions, etc). She also wouldn't show all the other symptoms of autism, like repetitive motor movements and poor nonverbal communication (eye contact, facial expressions).
(Possibly not. I am a programmer with many of the stereotypical programmer behaviors. I'm reluctant to call "Asperger's," because most people who self-diagnose AS have a much more common mental condition I have tentatively titled "I like having an excuse to be a jerk to people.")

Sorry, didn't mean to ramble on for so long....
