Can I still charge my own client fee on top of the lender commission?

Yes. You are free to charge your client a fee in addition to any commission the lender pays, and that fee structure is entirely up to you. Many brokers charge a flat consulting fee, typically $1,000 to $10,000 depending on the loan size, while others charge a percentage of the funded amount, usually 1% to 5%. For bank deals where the lender does not pay a commission, charging the client directly is the standard way to get paid.
