Yes. And no.
Yes, any of us can probably play fretless. It isn't that hard, after all. At the same time, it is more difficult. Finger placement is far more critical than on fretted. Fretless is much less forgiving of sloppy or bad technique.
Not all of us are great at hearing pitch errors. I don't hear pitch errors as easily as others so I may think I'm sounding fine when in fact I'm out of tune. I've had to really pay attention to my L hand technique and to really listen for those subtle pitch errors that others hear with no problems.
In the end I find fretless to be more of a challenge than fretted and that is exactly what make it more fun.
