Question:

Can the Germans trace general supply across the Swedish border to the
captured supply depot that they get in Sweden on turn 2 or must that depot
be in Norway to act as a supply source?

Answer:

No German unit at all can trace supply TO any depot anywhere at all! See Rule 11B1, 1st paragraph, 2nd sentence: You trace supply FROM a depot TO a German unit. Perhaps the question was phrased fuzzy? ;-)

The German player may trace supply FROM the special “captured” depot to German units, even if this depot is in Sweden. (Historically, the depot in effect always remained in Sweden and thus was crucial to the Germans holding out: they ended up sitting in the mountains at 25B:1010 next to both Narvik and Sweden and thus had guaranteed general supply, since the Allies were not going to violate Swedish neutrality to try to cut the supply flow.)
