No: The main causes of oral cancer are tobacco use, alcohol use, human papilloma virus and genetics. Chronic sun exposure is also a risk factor for lip cancer.

Unlikely: Repeated trauma to the same area over and over can definitely cause permanent changes to the tissues. These changes can be on a cellular level. In some cases, these changes can become a permanent part of the dna. So, in theory, this can lead to cancer. If you have a lip biting habit, you should get some help to stop. Also limit additional risks, like sun exposure, tobacco use, piercings, & so on.
