Yes, it's similar to a regular pot.  You can use two terminals to make a variable resistor (or you can short one of the end-terminals to the center-tap). 

 Just make sure to stay within the voltage & current limitations for the digital pot.   When I hear "rheostat" I think of high-power applications, although that's not always the case.

Thanks,
I jump a mcp4261 to uno, can't get the R readings, any circuit?
