Probably, but FPGAs/reconfigurable logic can't be clocked at CPU speeds and usually have a limited number of floating point units and other "hard" resources. At the higher end, yes definitely, especially packet switching, sniffing and other tasks that don't involve parallel ALU/FPU calculations. At the lower end FPGA's can still shine on applications that have precise/low-jitter timing constraints. For example, sampling an analog signal for frequency analysis, actuating a thing within X nano/microseconds of some event, regulating clock drift with the pulse-per-second GPS signal, etc.
