Sure, but you cannot control what someone does with their newly acquired money...
So if someone gets "tainted" money from you and deposits it in a CEX/bank (some people want to liquidate BTC for fiat, or buy instantly BTC with fiat), then you should expect a call.
But, how will anyone know who I am. Perhaps you mean if I buy something online. Well in that case, I will just lead the "interrogators" to the address that sent them to me.
In general, if we buy the whole "tainted bitcoin" idea, then we deserve the strict banking system that we currently have!
