No, it should be similar.
That's because XFAB got the process from Zarlink, which got it from Plessey, which got it from TSMC. So, XFAB got it from TSMC !
From my own experience I can say that there is nothing as "identical" process if run in different fab - perhaps Intel has it.
I believe that there will be minor differences but nothing really big. Another think is that Xfab has two fabs - Lubbock and Erfurt which are slightly different.
