No, no, it isn’t. By definition, cheese is a dairy product. It doesn’t have to come from cows, but it does require milk from an animal. Ergo, cheese cannot be vegan, which means that vegan cheese is an oxymoron.

Edit:

Found a site that links to a pdf covering what is and isn’t a cheese, legally. www.cheesesociety.org/events-education/cheese-definitions, and covers some of the terminology around cheese and cheese making.

If anyone can’t find an online dictionary like Webster’s, the oed, or other generally accepted authoritative source to see the range of standard definitions outside of regulatory of industry terminology, well, you probably shouldn’t be online at all. But, even the ones that include fake cheeses will state that it’s a non standard usage.

Plus, you can call smegma dick cheese all you want, but it’s still not actually cheese.
