After much searching and a bit of trial and error, I've got the auto-rotation working properly on my Linx10 and Linx7 devices when using Windows 10 Enterprise 32 bit.
I downloaded the Kionix KXTJ9-KXCJ9-KXTJ2 Windows (7/8.1/10) Drivers from here - You need to be registered to view this link, please log-in or register - and then created my own .reg file as the permutations previously suggested in this thread didn't quite work for me. The software package must have been updated again, but the default settings on first installing the drivers still leaves the screen rotation on the tablet out by 180 degrees. The previously suggested registry fixes offer a variety of new screen orientations, none of which properly correct the default behaviour.
After the installation of the x86 package and a restart, the registry file which needs to be applied to the tablet is as follows:
Windows Registry Editor Version 5.00
Restart and all should work as expected on both Linx7 and Linx10 tablets.
