"fuse" implies that the CPU will stop working when it is overclocked, this seems to be more of a mechanism for AMD to let them know that the reason the CPU is not working anymore is because it was overclocked and fried.
It's just an electronic component, like resistors and transistors. Samsung has something similar in their phones called Knox.
But in the world of electronics fuses and circuit breakers exist to trip when too much voltage is applied to protect the circuit. That's their generally agreed upon definition.
A fuse is just an electronic component. It can be used for circuit protection, but it doesn't have to be. For example, a transistor doesn't have to be an amplifier, a resistor doesn't have to be for dimming bulbs, etc.
