Can the battery in a Lenovo yoga 10 tablet be removed and renewed?

Yes but with difficulty and tech know how. I wouldnt fancy my chances at getting apart, putting it back in and getting it back together again though. I don't think i would bother.

I do not know technically about this model. If the covers are screwed then just a Phillip screw driver and plastic wedge will easily get into it but like most tablets it is probably glued, and a heat gun will be required.
Once in it will be very straight forward

Yes and it's fairly simple go on YouTube and Google how to change a Lenovo Yoga Tablet battery then get the battery off of eBay and do it it takes every bit of five minutes
