Absolutely. Do it all the time coming down off of Wolf Creek Pass, etc.
If you have over 80% battery, and do long, sustained, downhill regens, you can hit regen limits that are similar to Supercharger taper charging limits. It's an obscure limit, but I have had it happen with a full charge out of Pagosa heading east over Wolf Creek Pass, and leaving Aspen with a full charge, heading east over Independence Pass. This limit is not an issue for short, pulse regens, and only happens on long, sustained regens.
Enjoy!
