Would it be sufficient to assure equipment is clean and validation not executed for the cleaning procedure when clinical trial lots are manufactured in facilities used for commercial API production where other cleaning procedures were validated?

For clinical use APIs, you may not have the number of batches or the number of campaigns to show the consistency of that cleaning. However, it would be expected that you have each of the other aspects of cleaning validation for the new compound. While not asking for validation for the clinical compound, Q7A would expect a thorough verification each time you clean to supplement your commercial product cleaning validation.
