Yes, you'll get more than 18, but the overhead of the leader and trailer is the same for a 10 exposure roll as it is for a 36 exposure roll. Bottom line is that the longer each roll, the more total frames you get from that 100 ft. The practical limit for each roll is 36 exposures due to the limitations of the cassette, the camera, and the processing equipment.
