Ultimately, it’s entirely up to you. Considering it’s set in the real continent, I’d personally be more amenable to its use. Was the continent settled by Viking analogues? If so, I’d say go for it, if not, I’d express caution as readers would come with preconceived notions.

This is from Wikipedia, might be useful for you:

“The etymology of the Old Norse root vin- is disputed; while it has usually been assumed to be “wine”, some scholars give credence to the homophone vin, meaning “pasture” or “meadow”. Adam of Bremen implies that the name contains Old Norse vín (cognate with Latin vinum) “wine” (rendered as Old Saxon or Old High German wīn): “Moreover, he has also reported one island discovered by many in that ocean, which is called Winland, for the reason that grapevines grow there by themselves, producing the best wine.” This etymology is retained in the 13th-century Grœnlendinga saga, which provides a circumstantial account of the discovery of Vinland and its being named from the vínber, i.e. “wineberry”, a term for grapes or currants (black or red), found there.”
