It makes sense but is highly improbable. Having ATRAC "hard wired" and "programmed" into the ECU is one thing, while having a rear locker installed but not listed on the invoice would be wasteful on Toyota's part.
Obviously, crawl under the FJ to look for the rear locker, if its there and there is no switch, you may be onto something. But, that would mean you really got away with something for free...
