Without getting into any security infringement the Odometer for OLMS is hard but there are other things that work with it and store other info relative to it.

As far as the '10 software on the 09 ECM, the only way that would work is if it was a new green unit and you loaded it and even that is short lived. The unit will load but once the MEC decrements down to 0 and turns security on the unit will be a paperweight for all intents and purposes. It will run but more than likely with a RAM error however it will be unable to be re-written past this point.

This was the issue that Corvette owners have run into as of late I'm sure others in the aftermarket have encountered this as well as I've seen a lot of these units with '10 software on them from people trying to add launch control to the 2009 Corvette.
