quick basic, maybe silly queston?

fat32 file systems have no way to store Linux special file attributes.
These include character device files, named pipes, fifos, and sockets.
fat32 can also not store permition information; and under a unix-like 
operating system this is a must.
It also can not store owner and group information for a file; and file size 
is limited to 2gb.

You can also not store symbolic links or hard links on the file system; 
these features are almost required with modern Linux distirbutions.

There are horrible cludges to get Linux to run off a fat32 file system such 
as umsdos and similar; however the lack of fault tolerance on fat32 will 
mean if something goes wrong recovering will be that much harder.

You can run a Linux system on as little as a gig of disk space; (smaller if 
you want to cut corners) and the rest of the drive could be for dos.
That said; most dos systems run in aproximately 200-300 megabytes of disk 
with all the stuff you probably want installed.

You can of course have separate hard drives for each system; however this is 
usually overkill; partitioning the drive is usually all that is required.
Watch out however; a bug in real dos 6.22 and earlier won't let you boot a 
dos partition past the first 2.1gb. I found this out the hard way.

In fact it is possible to run dos inside Linux; check out dosemu; it is 
possible to get screen readers working inside here too.
Regards, Kerry.
