Clamping to carbon is generally considered to be a Bad Idea. Your seat stay will be hollow and wasn't designed with the thought that anything would be clamped to it. Crushing the seat stay is possible, though probably unlikely, and using a clamp would probably void any frame warranty you might have.
For peace of mind, I would think you'd want a trailer that attached via the axle...
