Last time I checked the only reason why racial names are changed is because of clear differences between the previous and the next race, so there had to be some. Judging by the Atmorans you can see in Sovngarde and the Nords that are there too, there's little to no difference between them.

Maybe the Atmorans changed their name because Atmora was rendered uninhabitable and they can't go back there, who knows. The whole Atmora/Nord thing is never really explained.
