I had CONTROL when I issued a mixed-airline ticket. HKG-HND on CX and HND-HKD (Hakodate) on a JL flight. So yes it could be other career on CX 160 stock.
My other thoughts are if your itinery is out of normal. In my case, award tickets are allowed 2 stop-overs but I wanted to stay in Tokyo both enroute to Hokkaido and on the way back. So I issued an award such that Tokyo-Hakodate segment return flights occur within 24hours such that my stay in Hakodate isn't considered a "stop-over". This way I managed to have 1 week in Tokyo, go to Hakodate for 24hour trip, back to Tokyo stay for another week.
Let me gurantee you those Manila MPC staff won't know this is allowed within award rules.
