Roughly, Scandinavian refers to mainland Europeans who speak a language derived from Norse. Scandinavians are the majority in Denmark, Sweden, and Norway, so those are Scandinavian countries, and a minority in Finland, so that is not. Tove Jansson, Linus Torvalds, and Michael Widenius are all Finnish Scandinavians, apparently.

Nordtech sounds right, though. I imagine that various places have already been dubbed Silicon Fjord, Silicon Sauna, etc.
