Will a front rim from an '04 SV650 fit an '01 model with no mods?

Nope - rotor offset and spacers are different. They generally cost more as well.

can you change spacers and disc carriers, to make it work?

If you're asking me, I already ordered the correct wheel from Nudist, so it's not an issue now.

It would be good to know about compatability without modification between different bikes though.

Bearings, spacers and shim the disks, IIRC.
