can a 32 bit process use more than 2GB?

As I said before, there are techniques that applications can use to deal with huge files larger than the available addressable memory.  

You would need to check the documentation and/or give it a try yourself to know whether vim specifically is written in this way.

If it can't, do some research and find an editor that can or split the file into smaller pieces.
