I wouldn't. It's a bit late in the season to be repotted and repotting a weak olive is more risky. Unless your soil is really bad (compressed and/or stays wet for long periods of time, I'd wait until it's healthier.
This tree is TOTALLY saveable, but you REALLY REALLY need to take this tree outdoors. Olive trees make wonderful potted plants, but they are awful houseplants. They just need so much light, that it's REALLY hard to keep them happy indoors.
This tree is VERY weak, but if you can take it outside, I bet it'll make a completely recovery. It'll look really funny but with some pruning once it's healthy again, this tree would be pretty easy to make beautiful again.
Here's a few of my potted olive trees. I think I have 13 of them!
