Maybe they took their name from there, but it's not the same. And this is the last post about this from me, because it's getting too much off topic.The actual Romanization of the Elite 4's title is Shitennō, which does actually translate relatively literally as Four Heavenly Kings. Elite 4 is just a Western take on the name, in the same sense that Pokemon and human characters have distinct names from their Japanese counterparts that usually have at least mostly the same meaning. In this case, calling them the Four Heavenly Kings in the west probably wouldn't have been the most sensible choice, since we wouldn't be able to pick up on why they're called that.
Unless you want to argue that Buddhism should be calling its Four Heavenly Kings the Elite 4 instead, since that's where Pokemon took the term from in the first place.
