If you meet the requirements under 61.51 to log the time as PIC (which on the CRJ means a type rating as well) then by all means log it as PIC. As we should all have learned at our mother's knee, LOGGING PIC has nothing to do with BEING PIC and so all the people getting their panties in a wad about Part 121 designating the PIC and the flight release and whatever else you're getting all excited about are wrong.
Airline's will ask you to complete an application form, on which they will ask for various types of time, and if they have a definition of that time that is different from the FAA's they will tell you - many of them consider PIC to be only that time you "signed for the airplane" - which means ACTING as PIC. Many of them don't count PIC time logged as an instructor, should we not have put that time in our precious logbooks as well? Airline interviewers aren't stupid - when they look through a logbook they are looking for correctly logged time - as long as the time was correctly logged according to the Federal Aviation Regulations they'll be fine with it - AS LONG AS YOU DID NOT MIS-REPRESENT THAT TIME ON YOUR APPLICATION - now that would be a problem.
