Of course it could, unless getting the ID of the cell phone tower itself requires data usage. You could put the cell tower locations in a database (which could be updated, of course) just like GPS vendors have done with map data for years.
However, given that Google Maps keeps its maps on a server (and therefore requires data usage to get the maps), it makes sense that Latitude also stores the cell tower database on a server.
