Historically this was not a problem. But in recent years some programmes have started to impose restrictions. Even so I would expect those restrictions to not really be an issue when you're flying with partners like this. As long as you have your physical UA *G card you should be able to get into lounges and flash it at priority boarding time etc. Once upon a time that's how it worked all the time but now you may meet lounge dragons that just scan your boarding pass and don't want to start looking at cards. But I would expect to see that in N.A. more than in Europe and I would guess much more than in Asia.
What UA and other airlines have really started cracking down on hard is using *other* programme perks like upgrades or waived fees etc. They threaten to pull your upgrade if you switch the FF number on the reservation.
