Nope. Like Koyote posted you'd have a bunch of other damage as well.

If anyone cares, this is how I've seen carbon frames produced (at more than 1 facility). The pre-preg carbon comes in large rolls, they're stored in big ass refrigerators. The rolls are taken out when needed and all the little bitty and not so little bitty pieces are cut on a roughly 4 x 8 CNC cutter. Incredibly accurate, incredibly repeatable. They differ some depending on size and of course model of frame. The carbon pieces are then labeled and put in a bin. They go to production where the molds are. The person building the frame puts the pieces in the mold according to a 'layup schedule'. It's basically a binder with 'this piece goes here and that piece goes there' instructions. Every frame is done this way so it's pretty hard to screw one up. Also, the frames are produced in production runs so at any given time only one model and possibly a couple of sizes are being laid up. Again, this doesn't bode well for mistakes. It's not like 10 people are working on 10 distinctly different frames and the wrong collection of carbon pieces could end up w/ the wrong person/mold. Seeing as how this is done it's very hard to imagine that a worker doing lay-up could 'forget' to put a few layers in a seat stay as they'd have extra parts in the bin when they thought they were finished. So, again...the likelihood that this was genuinely a warranty issue are very minimal.
