Short answer is yes but you need a way to tap into the tractor hydraulic supply and you will probably need to update the control valve on the loader to one that supports power beyond operation. Not terribly hard or expensive but the devil is in the details.
Another option might be keep the loader pump but use the tractor sump as reservoir. Probably less expensive.
A few pictures of your current setup would be informative.
