I don't think so. I've only done one curved project and what I did was to take the peice that I wanted to curve and rip it with a bandsaw into several thin strips. You then take the thin strips and glue them back together bending them around a jig with plenty of clamps holding it in place. If you only kerf the back it will snap at one of the kerfs. I would practice on a 3 or 4 foot peice of scrap to get the process down before trying it on the real thing.
Edit: Another problem with just kerfing it is the wood where it is not kerfed will remain rigid and put more stress on the kerfed portion. I hope this makes sense.
