Yes. A broker can share a fee with a principal in the form of a rebate, regardless of the principal's profession or license status. However, the broker is not required to do so. A rebate of part of the broker’s fee to a principal is a business decision made by the broker. If the broker elects to rebate a portion of their commission, the broker must comply with TREC rule 535.147(d).
In this case, since the rebate is going to a buyer who is not your client, you would need your client's written consent prior to paying the rebate, and the intention of paying the rebate would have to be fully disclosed to the lender, title company, and any government agency that might be involved in the transaction. Generally, a buyer's lender must approve of the buyer reciving the rebate, and whatever amount of money the lender does not approve cannot be paid.
