There'd be no formal (that is, passport or visa related) problems with this plan.
Whether a 10-hour layover is enough to get value for your (or your employer's) money out of Paris is something you will have to decide for yourself. Depending on how risk-averse you are, a significant part of those 10 hours could be eaten up by getting from and to the airport, waiting in security and passport control lines and so forth.
Then waiting in line for the Eiffel Tower can itself take hours on a bad day, unless you book a skip-the-lines tour in advance ...
