[ASOIAF] If Torrhen Stark had not bent the knee to Aegon I, could the North have preserved its independence through guerilla warfare in the same manner as Dorne did?

Only until the next long winter.

Survival through the winters in the North relies on stored food, usually stockpiled within the various castles. If Aegon gets serious about defeating the North, he just needs to wait until the snows come and then burn every castle. After a year or so, most of the Northmen will have starved and the survivors should be willing to surrender in exchange for a little food.
