These are not the same thing and need different terms.
Or, even if they were in some sense fundamentally the same, is your argument that their effects are so practically different that they ought to be called by distinct names anyway?
As I understand it, there isn't even a consensus on any theory of what autism fundamentally is. Some theories try to explain the social issues as a lack of Theory Of mind, but these theories don't cover the many other symptoms typical of autism. One more recent theory ('Intense Worlds') does present a 'fundamental' explanation for all/most symptoms, but AFAIK it's not well-accepted or supported by evidence (yet), and the fact that it explains so much is also considered a drawback (too vague / overfitting / whatever the term is).

I've noticed that there seems to be a movement in treatment approach that focuses on treating individual symptoms without focusing too much on the overarching 'labels'. In my experience it's been a very nice, down to earth approach, and it strikes me as more measurable too. This approach strikes me as particularly useful for autism because there's so much variation between different autists and the particular symptoms they exhibit.
As a result we're hearing the phrase "somewhere on the spectrum" for any number of behaviors we don't see fitting the norm, and the reality of autism is not this "beautiful mind" scenario for many, but instead a crippling illness like the AP mentions. They are definitely not the same thing to the people who live with them.
The article is completely centered around the media image that autism creates geniuses, and that's a dangerous, misleading idea at best. The reality of living with it is usually much more ugly. Children who often become grown adults who can't make connections between cause and effect violently lashing out, throwing feces, biting care givers, screaming, screaming, and more screaming.
We should absolutely keep looking for ways to prevent and try to treat/cure it, and not act like everything is fine and great and accept it as diversity, for the sake of those who can't live normally.
Beneath superficial success and contribution, my life is a nonstop Munchian scream. I find it less insulting when people say everyone on the spectrum should be exterminated, than when people say some of us should be allowed to continue existing because our particular end of the spectrum happens to write pretty code / invent pretty theorems / etc.
