Yes, my girlfriend ran into this last week.
The domestic lounge in YVR is pretty much just around the corner. I told my GF to go to that lounge with the guest pass, I really wasn't sure if it would work seeing as she had a boarding pass for LHR. Anyway, she said she got into the domestic lounge without any issues.
