Well "work" is a relative term I guess. Sure you can do it. Yeah, it might "work" if you take very light cuts as Don says in a pinch. Problem is there isn't a good way to know how light or heavy of a cut you can get away with before things go wrong. Also, the accuracy of chucking up an end mill in a drill chuck just isn't that great so unless you are just trying to hog out a slot or something your part isn't likely to be very precise. End mill holders and collets can hold an endmil and take the side load. Drill chucks are usually just pressed on a taper adapter (like a JT33 to a MT2). It doesn't take much side load on a drill chuck before it will let go from the taper adapter and go flying away.
