I think not. The only known Norse site in North America is L'Anse aux Meadows and from the documentaries that I have seen they say that it was only a temporary settlement and that they weren't there for very long. Maybe only a couple of years. The Natives seemed to have chased the Vikings out.
Greenland is normally considered part of North America. And the only thing that chased the Vikings out of Greenland was climate change.
