    Yes. The MB takes what it needs not what is available. Both are USB-PD compliant. May charge at different voltage from the supplied MacBook charger, but will not charge at higher wattage.
    I do it all the time and have checked above with USB-C meter.
    There is an Apple KB confirming as well.

    I am curious, is there no information from Apple, the manufacturer, available online to answer this question?

    Naturally they say use the one for your Mac, but go on to say higher powered one is OK.
