Yes you can but you are setting yourself up for a big problem. There is a reason the 20 amp fuse is blowing. By installing a bigger fuse it allows the current that is causing the 20 amp fuse to blow to stay in for a longer period of time. This can cause excessive heating and melting of the wires on the circuit that is blowing on a 20 amp fuse. Trace the wire and find the fault. Always use the manufacturer's recommended fuse sizing for your own protection.

Can I replace a 10 amp fuse with a 20 amp fuse in the AC?

No, you cannot replace a 10-amp fuse with a 20-amp fuse. Fuses are meant to guard your wiring and equipment by melting or 'blowing' before the wiring, itself, melts and causes a fire. It is safe to use a smaller fuse than called for, but never, ever is it safe to use a larger fuse than called for.

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.
