Oh, it's been out a while now:
There was a lot of confusion for a while right after the Yoga 720 and other 2-in-1s came out but, now, it's readily available.

Should be compatible, so long as it uses the AES protocol as opposed to EMR.
If it's the latest Wacom Bamboo Ink, you may need to hold the 2 side buttons for 2 seconds to switch from Microsoft Pen Protocol (MPP) to AES.
I have no experience with the pen but it has been reported (by SurfaceProArtist.com) to be better to use with the Lenovo Yoga 720 than the Lenovo Active Pen 2.

The Bamboo Ink works out of the box with the Yoga 720 15". It's in the Windows mode by default, or at least mine was, and works straight away.
The Wacom Pen options didn't work the first time I played with them, but the following day they did work. Maybe it needed a reboot or reconnect.
All of the settings in the attached screenshot work properly, including the barrel buttons acting as left and right click (including while hovering).
