I don’t think so. The Vikings in North America probably made the same mistake the British and French made later on, thinking a similar latitude as “home” would have a similar climate. Big mistake.
Also, the Vikings in Newfoundland discovered only extremely hostile and aggressive natives. There was no chance to really leave any progeny. All the Vikings left, or died, as far as is known. If a few Vikings “went native” they would not have left a discernable DNA footprint.
But if Vikings had sailed further south, say to Long Island or the Chesapeake Bay, history could have been radically changed with the introduction of iron making, the wheel, and the horse into North America 500 years before Columbus.

Actually, the Vikings penetrated DEEPLY into North America. I don’t know if the team name, Minnesota Vikings, was named for later Scandinavian immigrants, but the Vikings DID reach Minnesota. And enough went native to give the tribes that gave me a very small amount of Indian hair a propensity for red hair and creation myths similar enough to Christian ones to inspire idiot ufologists.
The Diocese of Greenland (I know, not L’anse aux Meadows, but much closer to Newfoundland than Iceland) included Labrador and existed until shortly before Christoper Columbus, 500 years later. In fact, LEIF ERICSSON* WAS A CATHOLIC BISHOP. (*Around these parts, we go with Erikson, but it’s legit.)
Good points. Funny you mentioned Long Island. That was a point of entry for the undercover Nazis.
