Yes seems likely related. The Rus' people are believed to have originated in present day Sweden. Does not feel impossible that there were trade routes connecting Greenland to Kyiv theough Scandinavia.
The Vikings went quite farther than Kyiv, as the existence of the Varangian Guard [2] (part of the Byzantine army) attests to (Varangians was the name the Vikings were known by in the Bizantine Empire). And as we know, they also reached the Canadian coast [3], so it's not the least surprising to me that their trade extended from Greenland to at least, Kyiv.
