The size of the map shouldn't be a big problem, what is more important is the number of active objects on the map. But such a big map might not be really good for organizing the game, there are advantages to keep things smaller. I think it would be better to make a good design about your game world, and make it so that you can start with one small part of it , and latter expand, if needed. That's better than creation a huge world that never gets finished.
