My interpretation would be yes, but as these RLL's are sparingly used I'm sure there are some grey areas.

PWA definition of a RLL:

g. “Reduced lower limit line” (RLL) means a regular line with a value that is less than
23 the lower limit of his LCW that is constructed upon request to a pilot who cannot be
24 awarded a regular line within his LCW

Since it says it is a "regular line" I would assume you are free to avail yourself to all rights of a lineholder including oob ws/gs/ws/gswc/swap board etc. Once again my opinion obviously means nothing, if I was in that position I would call and get an official interpretation.
