That is not really true. Every appliance is listed based on the branch
circuit it is plugged into. The dryer may have some 14 gauge wiring in
it that was tested to be safe on a 30a breaker but when you put it on
a 40 or 50 you have exceeded the available fault current and voided
the listing.
I have never seen a fuse in a dryer.

given this line of thinking, we could never plug a lamp with an 18ga
cord into a 20a outlet. *I stand as stated.

Lamps are listed to be connected to a 20a circuit, if you plugged it
into a 30 you voided the listing.

The answer is in 240.5(B)(2)
(2) Fixture Wire. Fixture wire shall be permitted to be tapped to the
branch-circuit conductor of a branch circuit in accordance with the
following: *
(1) * * 20-ampere circuits — 18 AWG, up to 15 m (50 ft) of run length
(2) * * 20-ampere circuits — 16 AWG, up to 30 m (100 ft) of run length
(3) * * 20-ampere circuits — 14 AWG and larger
(4) * * 30-ampere circuits — 14 AWG and larger

The circuit breaker is directly related to wire size. Just re wire the
plug. Carry on as normal.
