No, but why not do it the easy way. Use a box wrench to loosen the bleeder screw to just snug, then attach a bleed hose to the nipple and route it to a container. Open the bleeder valve, push the piston back with your thumbs, then close the valve. This will purge that old fluid from the caliper and once you finish with the pad change you can do a complete system flush.

If you try to push the piston back with the bleeder screw closed the only path out for the fluid is through the tiny compensating port in the master cylinder bore. You'll need a screw clamp to push back the piston, and if the reservoir is near full the extra fluid can overflow the vent hole.
