Of course it could. Almost anything "could". But it doesn't, as of right now. This exact discussion first happened when the original iPhone came out. It's been a decade+ now, and nothing has happened to your ability to run whatever you want on a Mac. If this really happens to be some sort of frog-boiling conspiracy, it's progress must be glacial. Which doesn't square very well with the other usual criticisms, namely that Apple doesn't care about the Mac, and that they suffer from short-termism.
