I'd take those articles with a huge grain of salt. How could you distinguish a CEO with the courage to make an unpopular choice (e.g. layoff 1/3 of the workforce to save the company) -vs- a psychopath who does it to inflict suffering on others or to just establish dominance? How do you even measure psychopathic traits without defining exactly what "psychopathy" means and a rational ethic by which to judge the non-psychopaths (i.e. the "control group" or standard of normal)? Moreover, motive is not irrelevant to the question and not only is it not measurable by researchers, most people don't even know their own subconscious motives.

I'd bet if you dug into the research what you'd find is the research really shows that psychologists who study such things do not have the character/psychology of those who become CEOs, not that they are psychopaths.

Huh? You just give the ceos a psychopath exam.

No. I reject the methodology of the psychologists who do these types of studies.

Why?

Because you can't define pathology (deviation from a norm) without defining the norm. Modern psychologists dodge this question and implicitly assume various generally accepted moral standards and tenents (a form of circular reasoning) by which they condemn those who don't follow it. It is not science and to make it a science the psychologists should be seeking a rational basis to define ethics. Nobody has done this and until they do psychology will remain a pre-science like alchemy.

In addition, it would also be supremely discriminating if the "Psychopath exam" would, for example, consistently score Asians lower.

That is, a psychological or culturally acquired trait should not be used against an individual without a proof that it actually affects his behavior. You are in essence denying that the person has any agency and it's utterly incapable of learning and acting on society's moral code, which I bet is false for the vast majority of people with sociopathic tendencies.
