Yes. In the trial I described, I used a 225 F oven for about 2 1/2 hours to get the meat internal temperature to 165 F. Then I lowered the oven temperature to 170 F and, wonder of wonders, 8 hours later the internal temperature of the meat was, right, 170 F.
I did all that in a covered roasting pan in an oven.
But even on a grill, if have the internal temperature at 165-170 F, an air temperature on a grill of 170 F will, bingo, keep the meat internal temperature at 165-170 F.
