Could you edit the map on a world you have used priviously? Like: I explored mordor and edited rhun would my tower in mordor stay? And just anything i had in rhun deleted?

If you were to edit the map image then it would not affect any previously-generated chunks. The map image is only a reference for the mod to use when generating new chunks. This is why, when we add new biomes in updates, any explored areas in those regions from previous versions don't automatically convert into the new biome.
