Sure. Most adults can learn lots of things. Most of us only care enough and have time enough to educate ourselves on a very small subset of the tools we use and tasks we perform on a daily basis. By and large, I trust the tools I use out of the box to be safe (subject to what common sense typical functional adults would be expected to have).
It is often reasonable to provide the option to use tools in ways that are less safe. Sometimes that's unavoidable. You can certainly use a chainsaw unsafely although I also think it's perfectly reasonable for chainsaw manufacturers to not provide easy ways to defeat the various safety mechanisms that are built in.
So you'd only buy a chainsaw with a codepad entry where you have to contact the manufacturer and ask them 'can I cut this log'; ooh, so much safer! But where does that leave the people who been buying that brand of chainsaw for a decade or more and don't want the restrictions?
Just remove the codepad, well yes, so long as the manufacturer doesn't weld it on ... oh, and they just decided to weld it on. Such safety, much wow.
