Yes from over current from power surges, over driving by the user in case of amplifiers, or other component failure around the transistor. Also overheating can cause transistor failure from poor ventilation or loos heatsink.

Voltage amplifier
A PNP transistor has no advantage or disadvantage over an NPN transistor in its ability as an amplifier. Rather, the current-handling capacities of the transistor determine if it's usable as an amplifier.
