in theory if everything was 100% the same it would work. the OTS maps that you can get run on this concept and the tunes are rather conservative. if it is somthing other than a conservative OTS map then i wouldn't trust it. there are many factors that can make it unsafe on the car it was not intended. a few examples would be if the tune was done on one with a slight boost leak or a different load on wga, or one bov is more prone to leak than the other.. etc.
ninja edit: the actual rom may not work if you directly flash an 08 on an 10 etc but i was more referring to copying the tables and the tune itself
even if you could i wouldn't do it. not every car is the same. if you wanted to use it as a base, run some logging on the afr's, then edit the fuel maps for that car, then edit for knock, you could do something like that, but i wouldnt just slap it in then go and think everything is all ice cream and unicorn goodness
