No, cable tension would not be sufficient to prevent the adjuster
barrel from turning. It's probably corrosion in the threads. The first
thing I'd try is backing it out with a pair of pliers. Be careful
though since on the RSX group (at least on mine) the adjuster is
plastic.

No, on STI shifter/brake levers both cables can be removed without
taking anything apart. To remove the shifter cable first get the lever
into the gear with the least cable tension. On both front and rear
this is accomplished by clicking the inner lever a bunch of times. If
you've already disconnected the cable from the derailleur, pull on the
cable while you're doing this. Then squeeze the brakes and look into
the exposed innards, opposite where the shifter cable housing enters
the lever. You'll see a hole out of which the cable can be removed.
Pushing on the cable where it enters the downtube boss should cause
the little knob at the cable end to pop out of the hole.
Brake cables are also removed with the lever squeezed. Release the
lever on the brake that's used when you remove a wheel, or on
cantilever brakes detach the cable at the brake. Alternatively,
disconnect the cable at the caliper. This will allow you to squeeze
the lever fully. Look into the innards of the lever from the front and
you'll see where the knob at the end of the cable seats in the lever.
Pushing the cable into the housing at the other end should push the
knob out of the lever.
