This is not a good idea to do. Sometimes just that little bit of extra current that the 45 amp fuse will allow to reach the 40 amp load might be enough to destroy the device.

Can a 30 amp fuse replace a 40 amp fuse on a lawnmower?
You can replace a higher rating fuse with a lower rating provided it works with the device without constantly blowing. So try the 30 amp fuse in your lawnmower and if it doesn't blow and the mower works okay, you are fine. If it blows you will have to go back to 40.

Can you replace a 15 amp fuse with a 30 amp fuse?
Not a good idea. The 15 amp fuse will be protection a #14 wire which is rated for 15 amps maximum capacity. By changing the 15 amp fuse to a 30 amp fuse you would then be allowing 30 amps maximum capacity on a #14 wire. By doubling the load the extra heat generated on the smaller wire could be enough to melt the insulation from the wire and that could cause the wire to short out. If the wire shorts out inside the wall it means the removal of the wall board to replace the wire to restore the circuit to an operational condition. The proper wire sizing for a 30 amp fuse is, #10 copper wire with an insulation rating of 90 degrees C.

It should work with a 20 amp, just not as long. Wipers use a fair amount of current so the factory puts a 30 amp in. Perhaps that particular 20 amp is bad or it blew as soon as you turned the wipers on.
