Hi,
You're usually better off emailing the departments in question but I've been directed this way anyway. As the B Line card has the government pass logo on it, it's valid, as long as it shows your name, date of birth and a photo. I unfortunately struggled to find a clear picture of one so can't tell if it has those elements. If it does, then yes, that's fine. If not then no.
Kind regards,
