yes, they can, unfortunately only by means of piecewise approximations of the nonlinear function using special ordered sets. This technique is quite powerful, but the accuracy is compromised when the number of variables is reduced. Furthermore the problem is no longer purely linear programming since it becomes mixed integer programing due the requirements of the SOS to handle on/off variables.
