I got a Yoga 720 13", i5-7200u, 1080p display, 8 GB RAM, 256 GB SSD model from bestbuy. I can run Ubuntu 17.04, Mate desktop out of the box with almost everything working as expected. I first tried it in a LIVE USB session and then installed it to the SSD. I created a Win10/Ubuntu dual boot setup as follows.
(1) After booting into Windows for the first time, download and install all updates.. The pre-installed Lenovo service utility prompts to update the firmware. I went ahead with it.
(2) It is necessary to change the storage setting in the BIOS from RAID to AHCI, in order for linux to recognize the internal SSD. As the pre-installed Win10 was installed in the RAID mode, chaning the mode as above will break Win10. In order to prevent this, before changing the mode, follow the steps outlined here to switch Win10 from RAID to AHCI without reinstallation.

Alternatively, you might make a fresh installation of Win10 in the AHCI.
(3) After switching Win10 to AHCI shrink the single windows partition using Disk Management utility to the desired capacity and make space for linux.

(4) Boot with Ubuntu Live-USB from USB 3.1 port. I installed Ubuntu in the UEFI mode.
(5) Using gparted, create desired partitions. I created 3 partitions. (root installation, /home and swap) and perform Ubuntu installation.
(6) The dual boot setup is now ready! Upon rebooting, the UEFI boot menu shows options to boot into linux or windows. With Kernel 4.10 in Ubuntu 17.04, most of the things works out of the box as a laptop. (Wifi, sound, mic, suspend/resume, touch screen) I haven't yet fiddeled around to see if it correctly works in the tablet mode.
(7) Update Ubuntu using the standard commands,
sudo apt update
sudo apt upgrade
I am yet to test this setup thoroughly, but the command,
acpi -b
estimates the battery life >7 hours, in the idle mode.(medium screen brightness, wifi on, browsing in Google chrome/editing documents,no videos or cpu intensive tasks) Normally I keep the AC supply plugged in while working indoors.
(8) It seems that the battery is discharging faster than expected in the suspend mode. 2% discharge after 10 hours of suspend. I am investigating this.
I hope these instructions help someone to setup dual boot in this laptop!
