Now if you are removing your polish with pure butyl acetate (which is hard to get a hold of and almost no one has) then yes, thinning it will work fine. Most people pick up their drugstore brand or order it from their favorite polish company. The problem is not only the different solvents but also the potential added water, fragrance and/or oil.
I have tried to thin mine with both acetone and remover in the past. The funny thing was that most of the low end polishes were fine but my expensive ones went bad. I am not sure if I would call it curdling but it definitely ruined them. Well that hit me right in the wallet so I decided to opt for thinner instead and I haven't had a problem since.
