The trick is probably the voltage. It's very probable that all the "working" chargers in your list can supply 15V or 20V, while the chargers on the "not working" list probably top at 9V or 5V. Unless the laptop has a circuit to boost the voltage to the battery voltage, it will not be able to charge. The statement works better if it's restricted to "for modern laptops, USB-C makes it possible to charge with any laptop USB-C charger".
