The stem is very long and puts tremendous force on bearings that were designed to take a much smaller load. While you are unlikely to snap the stem on a Swift, you may well damage the headset. The one small wheeled bike that allows you to pull is the Moulton. It has a head tube the size of a paper towel roll. But it's not a folding bike.

Bike Friday owners will here will tell you they stand and pull all the time. Birdy owners, too. But if you talk to mechanics, they'll tell you that they've seen quite a few ruined head tubes.
