Narrative:

Location: runway 10 and taxiway a, pre takeoff. We were holding short of runway 10 full length with a wheels up time of XA07Z. 2 planes (B737 and a learjet) taxied behind us that needed to take off before we could. Tower instructed us to taxi onto runway 10 eastbound and exit at taxiway a holding short of taxiway east so that another B737 could taxi by us on taxiway east to full length runway 10. We followed tower's instructions and held short of taxiway east on taxiway a. As we stopped, we questioned whether the tail of our plane was across the hold short line. We told tower that we were not sure about this situation. Tower told us that if we were pulled up to taxiway east that we were ok. The captain opened the window and looked back to see if our tail was over the line but could not tell. 2 planes took off of runway 10. The wbound B737 taxied by us and tower cleared us to taxi back to full length runway 10 on taxiway east. As we turned the corner and looked back (now that we could see the hold short line) we both agreed that our tail was probably over the hold short line when the 2 planes took off of runway 10. Supplemental information from acn 511837: there was no part of my aircraft within 100 yards of the runway, but the hold line is painted far from runway edge. Runway 10 is a CAT ii runway, but I saw the markings as a runway safety area hold line and not as a critical area hold.
