I think it is different. Norway is still there and is still a real country. Frozen didn't replace it. They added a fictional fairy tale ride to the area with a fictional city. Yes, we can argue about whether or not it is truly Norwegian based but if you have watched any of the extras on the Frozen DVD or BluRay you can see that Disney believes it is. Wakanda on the other hand is complete fiction.Wakanda in World Showcase is not different the Frozen in World Showcase.
