I'll leave it to M2dude to answer this fully and properly..
But... yes and no....
Whether you could actually continue the take-off, if one reheat didn't light, depended on several factors, such as t/o weight, runway length, ambient temperature, and suchlike. This was all calculated before take-off, and there was a little tab on the forward panel (I'll have to find a photo), which you would flip to either "3" or "4" as an instant reminder.
If the little tab said "4" and you got only three reheats coming on, you didn't have to think or go through a checklist... you rejected the takeoff.
M2dude probably can quote the speed.... but it was still well below V1, so such a RTO was not nearly as spectacular as a really nasty one around V1.
