Daniel, I dont agree...
The resistance of L101 is 2 Ohm and with a good short circuit in C107 and D108 the voltage rise will be limited by the voltage drop over L101.
If the supply voltage is disconnected fast enough the damage should hopefully be limited to C107 and D108
To operate a 6.3V tantalum capacitor at 5V should not lead to a failure, unless the capacitor is faulty
