Sort of. Wayne has Schrader valves on his Brompton, and the push botton on the Lezyne chucks works a little different with them. I can't describe the difference any better than Lezyne; "When using an ABS equipped Lezyne floor pump to inflate a Presta valve tube, pressing the ABS button releases the air back pressure. Releasing this back pressure allows for the easy removal of the Flip-Thread Chuck without the risk of unscrewing removable Presta valve cores. When inflating Schrader valve tubes, pressing the ABS button releases air from the tube to adjust tire pressure". Note the last part, that's exactly what he doesn't want to do.
Switching to Presta tubes with adapters (metal or rubber grommet type, depending on rim construction) and using a Lezyne floor pump with their optional press on right angle chuck (Presta only) might be another option, but I can't directly vouch for the fit/ease of use because the current designs didn't exist when I was riding Bromptons. I never really found anything I was truly happy with back then, but I have used the described combination on 18" and 20" geared hub and generator hub and 36 spoke wheels (which also have access limitations), and so far I'm liking it. Lezyne pumps in general are hard to beat.
Schwalbe tubes with all metal stems seem hold up better than some other brands, particularly in applications involving friction chucks that have to be pulled off (while also appearing to be superior with twisty type chucks too).
