The datasheet states that TPS2400 protects the load from an over-voltage, by disconnecting the load from the power supply (Q1 goes off), without blowing the fuse. Why is the fuse F2 here, if there will be no current flow at over-voltage or under-voltage condition?

Fuse F2 protects against over-current conditions, which can occur when the voltage is within normal limits. Imagine a short in, say, D2. That short would draw excessive current and blow fuse F2.
