One can, but it means more extension and issues with large prints on some set ups. Arguably the resolution is lower on longer lenses too (according to Ctein and others) but whether this matters a lot I don't know.

With LF, I have often printed 5x4 wide open, or close to, with my 150 rodagon with no issues, but I would not do this will small formats. My 105 Rodagon is incredible wide open, but the same cannot be said for some of my others wide open! I guess 'it depends.'
