Dumb PCM Question

If you use a spare PCM, Does Ford have a memory program inside the PCM for mileage cross reference. Back in the 80's Dodge would compare Odometer reading to PCM reading, if off by a certain amount your warranty was void.

I don't know how true it is on an episode on CSI Las Vegas they took the last reading on the car computer (it was an Ford Expedition) and it told them that it traveled 23 miles.
