For the metrically inclined:
40 inches = 1.016 meters
25 yards = 22.85 meters
40 yards = 36.576 meters
1 inches = 0.0254 meters or 2.54 centimeters
1 yard = 0.9144 meters

Nothing good. It would damage the choke and possibly banana peel the barrel.
Chokes are removable, and it would be advised to remove them for shooting a slug.
Not all chokes are removeable. If you do have a modular choke you’ll damage your gun faster firing without a choke tube in place faster than by firing slugs through a full choke. They make thin wall choke tubes if you want to have an open choke with a modular choke system. From my admittedly 2nd hand knowledge rifled slugs through full choke is safe, but generally inaccurate.
Yup, I have shot slugs from choked barrels on many occasions and it works just fine. Some shotguns shoot rifled slugs a little better with a modified choke than a cylinder choke.
