Please refer to the previous post.
I found it necessary to install a previous version of Linux Deploy. linuxdeploy-2.0.0-216.apk
Then I needed to visit Google Play and turn off automatic updates.
Go to Settings | Apps | Linux Deploy on the Yoga Book and grant permissions manually.
Use a Root Browser to copy the SU file from /magisk/.core/bin/su to /system/bin/su and /system/xbin/su.
Lastly, in order to have VNC connect, I needed the password from Linux Deploy under properties, which is under the arrow down button in the upper right. See image below.
Best of Luck.
