There are no doubt FAR 142 facilities in Europe. If you receive a proficiency check from a person authorized by the FAA to give that check, then you are good to go.
But instead of betting your ticket on the opinions of strangers on a forum, why not check the faa.gov website and get the information from the front end of the horse. You should find a list of not only persons authorized to give the PC, but also facilities approved for the event.
Good luck and enjoy the flying in Europe!
