Do you have a part number or some other reference that would indicate exactly which choke pair you're talking about?
In general, the (physically) closer the chokes are the more flux they'll couple, i.e., the greater their mutual inductance. It's possible to build them at right angles and in separate magnetic circuits such that they couple only a very small bit, but fundamentally if they're close, they're very likely to leak to one another more than if they were further apart, all other things being equal.

They're almost certainly wound on the same core and you're looking at a choke with a tapping. If you have a means of measuring inductance, first measure all three possible resistances (you will probably have one large resistance that is equal to the sum of the other two). The measure all three inductances. You will almost certainly have one large inductance that is rather larger than the sum of the other two, and this indicates coupling between the coils.
So, the short answer is, no, you can't use one for one channel and one for the other.
