Nope, but there is a very cheesy way of keeping him but you have to throw him out before you go to rescue imeon. I havent tried this personally but i have heard it works on this very forum. What you do is throw him out before chapter 4, complete the quest and when you return to arthalka, go to ther copper cornet. I recommend to save now as the following gets tricky. Go in an pause the momment you enter, click on yoshimo who will be near the door at the time, before unpausing. tell yoshimo that you want him to return to your party and he will, but he will dye and as he is then in your party you can ressurect him. I personally wouldent take him, the other demi-theifs in the game usaully are good enough. Keep in mind you will have imoen at thi point.
