Of course there could. If you want that, you just run a Linux PAE kernel 
on 64 bit hardware. Each process runs in 32 bit task space with the 
kernel looking after the higher order buts in the address registers.

If you have 32 bit code that you need to run, this will do it. And, if 
you have no need to run freshly compiled processes with multi gigabyte 
memory requirements, they'll run too and be a bit smaller thanks to their 
shorter addresses.
