Yes, the value of a "lifetime" warranty depends a lot on the manufacturer's interpretation but Trek in particular has a reputation for being reasonable and not nit-picking excessively. They won't (really can't) replace an old frame with its exact duplicate but they will replace it with the nearest current version. And yes, stripping the old and building up the new frame is on the owner.
