Yes, you should be able to do it. Here is an example:

% gradsnc -l
ga-> open model.ctl
ga-> set x 1 72
ga-> speed = sqrt(ua*ua+va*va)
ga-> lats4d -o myfile -func speed -time 0z1jan1987 -vars ps
ga-> quit

and it will create a netcdf file named "myfile.nc" with a variable called
"ps" but actually containing the defined variable "speed". There are other
tricks you can play to have the variable name come right, but I'll stop here
since I don't know what you are trying to do exactly.
