The answer is yes “both ways” from a “safe” perspective …
… but you’ll probably find that the smaller adaptors just can’t keep up w/ your Mac’s power demand … and that it’s battery SoC will still be decreasing. (albeit at a slower rate)
The 20W power adaptor (w/ USB-PD) is certainly at THE bare minimum to even consider attempting.
The Mac might also throttle it’s performance if it “sees” a smaller power adaptor; I’m honestly not sure how that “piece” fits.

Thanks for that reassurance. I would only charge the laptop while not using it, just to give it some emergency power. Sometimes you find yourself without the right connector especially with Lightning so prevalent in my various apple items. Looking forward to a standard. Oh for the days of the cassette which was a rigidly enforced standard. We’ve gone backwards since in the name of innovation I suspect.
FWIW, I’ve used a 20W adaptor on the road w/ my own MBP for a couple of years now.
It can’t do a “lot” … but it CAN keep up w/ “most” tasks needed when away from the desk/dock.
FWIW? Showing my age I’m afraid. For when I’m working?
For what it’s worth. 🤫
And I remember how my AST “386” was the envy of the office.
Despite owning Macs since 1985, I had to learn so many operating systems including cpm. That died quickly. DOS almost made sense.
