Does the PD standard not regulate? I've used a PD power cord from a laptop to charge a mobile phone, but that isn't exactly a small device. And maybe I shouldn't have done that...
I think a phone is big enough that it can work with the PD charger. But I had a tiny little gadget that wouldn't pull any power from a PD charger, but did charge from a normal charger / dollar store cable.
You can certainly charge a phone with a PD laptop charger. PD does negotiate, so it will only give the device what the device indicates it can support.
I use my laptop charger with my android phone frequently if I'm out and about.
