The regular Express luggage service is only available from Zurich HB (the main railway station in the city center), not from Zurich Airport. Although it's a short train ride from the airport to Zurich HB, it may be too tight to get there before 09:00.
You'd better look into the Express flight luggage option, as that's available at the airport. Mind that your luggage can't be transported to Lauterbrunnen in this case, but to Interlaken Ost or West, so you can pick it up there by 17:15 or 17:30.
Links to detailed information for each service can be found at our luggage page.
