Correct me if I am wrong here, but if I recall it correctly, Jon Stewart made that name change himself (as your comment and linked source implies), while in Trump's case, it was not done by himself, it was something that his father had done in his life (or maybe even grandfather?). That is something fundamentally different, but Last Week Tonight is just some comedy show, so one should not expect too much here.
