No one comes in here to intentionally give people bad advice.
We have different opinions because we've each had different experiences. I have used lacquer thinner and acetone to remove old flooring adhesive from wood with no problems at all. As long as sufficient time is allowed for the lacquer thinner or acetone to evaporate from the wood or concrete, I expect it could be used successfully to remove the same adhesives from concrete.
