I do not think so as the "four kingdoms" are clearly meant to be spread over the entire world per Port's comments and the map in the prologue and Glynda explicitly talks of students coming from the "other kingdoms" to participate in the Vytal Festival. Weiss essentially repeated that in the most recent episode by talking about the festival celebrating the "cultures of the world" and wanting to greet people coming to their kingdom, implying the people arriving are from the other kingdoms.
