I haven't gone from a top mount to an under-mount, but it looks like you would be able to. The only fear I would have is getting the gunk off the top of the counter that will now be exposed and making sure that you have no visible trace of the old sink being there. I have no idea how easy that would be.
My under-mount is basically held in with some strapping that was screwed into the granite and then a silicone adhesive/caulk around the edges. I would imagine that you would get someone to do this for you though and they could do that part pretty easily as long as the sink holes match up and you have enough room underneath.
