Perhaps, but it happens all the time anyway. The hospital at which I worked just fired an employee who was pregnant because she was pregnant. The ironic thing is the person doing the firing is an administrator who herself was out for 6 months on pregnancy leave.

If the pregnancy interferes with that employee's ability to perform a specific job, and further reasonable accommodation cannot be made, then they may have been within their rights to let that employee go. Having a wife who is a teacher and two children, I know that being pregnant does not interfere with the ability to teach.
