I had real trouble finding a straight answer to the question of whether there were still problems upgrading to Windows 10 on the Yoga 2 Pro three years after it was released (I upgraded in August 2018). This post is just to add my positive experience so that others might find it when searching instead of having the usual problem that only negative experiences are reported.
So, basically I was moving from Windows 8.1 64 bit to Windows 10 Build 17134 and the short version is that absolutely nothing bad happened. I did have all my firmware/drivers up-to-date, so I didn't even have to make any changes there.
The only problem I have encounted is one that I already had, which is to do with Bluetooth cutting out maybe because of WLAN interference (seems to vary with intensity of use).
So overall I am happy with the result. Especially as I successfully used the tool described in this ZDNet article to perform the Windows 10 upgrade for free even though officially it stopped being offered on this basis years ago:
