I used to have a savings account with the Rabobank (which my parents started for me when I was younger). One day they called me to ask if I was still studying, else I'd have to change my account to a normal (paid) account. They stated that one of the conditions of using a student account was that your government student funding was deposited on your Rabobank account.
They were surprised to hear I had not been a student for years and never ever used my Rabobank for my student funding. Upon saying I'd have to change to a paid account, I cancelled my account.
Long story short: I don't know how strictly they check stuff, but for student related items they definitely do not check very accurate.
The best option would probably be, as mentioned before, to just create a calendar item in Rabobank that sends your salary to bunq.
