Best to post some pics but the answer, presumably without pics, is yes. Understand that selvedge denim is sewn straight on the out seam in line with the selvedge meaning that there isn't much shape to the leg. It's a very straight leg on the outseam. Even selvedge boot cut are pretty straight for a boot fit. So they can be tapered but if you cuff them, you may deal with an outseam that has a look of a wider selvedge seam area.
Personally, I have to do a ton of alterations to my selvedge jeans because I am not built straigh up and down. I cuff mine and they have a wide seam allowance from tapering them. I live with it....comfortably I might add.
