PNC probably could, but just barely.
The reason that Fenway can easily fit a field, if you think about the way the stadium lays, is that while Fenway has a very short left field and left center field, it is very deep from just to the right field side of dead center all the way to almost the first base corner. So you could run, indeed you would have to, run the field paralleling the first base line with the end zones by the third base dugout on one end and in right field on the other end.
Notice that that is not the way that a football field fits into Yankee Stadium. They run the field there from home plate to center field, because Yankee Stadium is short down both lines but is relatively larger from left center around to right center. The way a field fits at Yankee Stadium would not work at all in Fenway, and conversely the way a field fits at Fenway wouldn't work in Yankee Stadium.
Based on the dimensions, I think the only way to fit a field at PNC would be to do the opposite of what they do at Fenway and run the field down the third base line, so that one end zone was in front of the first base dugout and the other was in left field.
