Well, apples are plants, and the adjective "vegan", when applied to foods, basically just means "plants and fungi", so, by definition, yes. Trivially yes.
But an apple isn't a very interesting case. What's more interesting is what TFA is talking about: an increase in orders of entire meals that contain no animal products from restaurants. It wasn't that long ago that it wasn't even possible to do such a thing at the vast majority of restaurants in Western countries. It may not indicate an increase in the number of people who eat mostly or only vegan food, but it certainly indicates changing attitudes about what qualifies as a proper meal.
