You can use your awl or seam ripper's point to run along the edge of your stitching to crease/score the paper and make a line that will make it easier to pull apart....sort of like you'd tear paper against the sharp edge of the counter or table. I've done this before, though it's been years.
It's easier to remove when you use a very short stitch.....but who wants those very close together stitches in your quilting?
