Yes All versions of MameCE3 can run from Storage card. During the installation, choose no when it asks if you want to 'install it to the defualt location', then select storage card instead of main memory.

I install MameCE3 into Main memory and install MegaMamce3 to the storage card. Then I put the top 5 games I like in Main memory and I put the other 20 or so games on the storage card. This way I get a variety of choice with or whithout the storage card inserted. I do however have the iPaq 64MB model so I have a bit more space than others ;).

As someone pointed out, the only thing you absolutely need to have in Main memory is the Hi score folder (only if you want to save hiscores, otherwise even that does not need to be there). This is hard coded becuase it required a tweak to one of the core files (which I try not to make any changes to when possible).
The up side is, no matter where you install the Exe too, you can store your roms in any of the following locations and MameCE3 will detect them:
\Program Files\MameCE\roms\
\Storage Card\Program Files\MameCE\roms\
\My Documents\roms\
or \My Documents\
