Would it be okay to charge the 12" MacBook with the Thunderbolt 3 cable from the LG Ultrafine 5K display?

This delivers 85W of power. It charges the MacBook (even though the computer cannot use or power the display). But in the long-term, is it okay to just charge the MacBook this way?
 
It delivers up to 85watt. It can do less if the macbook doesn't need it all.
