yes. I've had a width difference on 2 different machines of the same brand. My inexpert analysis came up with two possible causes:
1) One or both of the 1/4" feet are not 1/4".
2) The needle adjusting settings are not identical on machines. Even with the little opening for the needle, I find I have room to move the needle to the left of center, right of center or center on one machine, another machine doesn't really give me a choice - it's a simple mechanical that i use on vacation, and my third machine is, theoretically, calibrated to work like the first one described, but it doesn't.
Make several sample blocks or seams from each of your machines and compare them using a 1/4" seam measure. Make a note of which needle settings are most compatible on each machine and tape them to the machine where you can easily see them and they won't interfere with sewing.
