I don't think they can run code at all.

At least that is how it used to be; some PDFs that we produce
for student quizzes have never worked with Apple's Preview.
The embedded Javascript would not run.
Perhaps this has changed in recent years?  I've not tested.

Also, the existence of a hidden button would screen a hyperlink
beneath, even when the button had the option checked to pass
events through. It is as if Apple deliberately chose not to support
PDF forms.

If this has changed then I'd really like to know the details.

Yes, it seems to be used the same way.

I'm using it to mean, sort of:

  "I think what I just said is true, but cannot really claim
   to know for sure -- so be warned!"
