The Negative Zone has been previously stated as being a universe that's linked to all the other alternate realities out there. So if you were to open a portal to the Negative Zone in the Age of Apocalypse world, you would reach the same Negative Zone as if you were to enter from the 616's portal. The problem is the Negative Zone is too big, and so it's very unlikely to find a different portal other than the one you came in from. Also, at this point, there are conflicting reports as to whether the Ultimate U's N-Zone is the same or different place as the Negative Zone. Personally, I think every writer other than the guy who came up with the N-Zone way back in the early issues of Ultimate Fantastic Four consider the two to be the same place.
