It's certainly possible.
Now bear with me, I don't currently have the time to translate wikipedia correctly onto here so enjoy google translate:
Swedish is a Finnish surname. While the West Finns were part of the Swedish Empire, the Orthodox Karelians called the Lutheran Finns the 'Swedes'. It was not uncommon for the surname to be given by someone outside the community. In the community, people were often known by first names, and houses were also often named after the first name of the founder or host of the house. Outsiders, such as travelers, needed different names to be able to navigate wider areas. There were Pentti and Antti and Pentti houses and Antti houses in almost every village, which made them somehow separate. An additional nickname was required. The general basis for the additional designation was domicile. Names could also be given to a prominent feature of the inhabitants, such as occupation, religion, appearance, or ethnicity. For example, Karelians could name a Lutheran house or settlement and their inhabitants as Swedish. When these names began to be inherited, they had become surnames.
