Change it. You don't know what type of oil or filter were used last. I would not trust running it long-term. It isn't expensive to do and it is better to be safe than sorry, imo.
I bought my car from a non-BMW dealer and I know for a fact they didn't use an OE filter or oil. Probably wouldn't have been a good idea to run a filter designed for 5-7.5k miles as long as the dash lights indicate.
