It is a Code requirement that they be run in the same conduit.

Could you provide a reference? I'm aware of the code requirement that
the Equipment Grounding Conductor for a feeder be run in the same
conduit as the current carrying conductors, but I'm not talking about
the Equipment Grounding Conductor.

Of course you are -- it's the conductor that grounds the subpanel.

No, I'm not, the SER cable already has 4 wires, including an EGC.
[This is in contrast to type SE cable, which only has 3 wires, no
EGC.] These obviously will all be run together, as the NEC requires.

I'm talking about the Grounding Electrode Conductor, which is a
separate wire that runs from the neutral/ground bar in the service
entrance to the earthing sources: Ufer ground, metallic cold water
pipe, and ground rod. Is it OK to run this conductor in the same
conduit as the feeder to my subpanel?
