20-pin omits the last four: 11, 12, 23 and 24) Color Signal Pin Pin Signal Color
Very possibly, but not recommended.
You would need to verify that with an ohm meter:
On the Motherboard, no other connects plugged in Pin 11 _> 10, Pin 12 ->1 and Pin23-> 22 read a short: Then Yes it should work, if not No workee.
Reason it is not recommended is the IR drop across the connector Pins (wires should not be a problem). If this IR drop is two high it could melt the connector plastic shell. I could give an example, but I would be pulling numbers from the end of me that sits on the Pot.
