Is the spring constant on the moon the same as the spring constant on Earth?

[OVB]

is the same as the spring constant on Earth right? My reasoning is that since Force is directly proportional to displacement, the k would remain the same. But we don't know that k is constant so I don't think that is a solid proof...

Yes, nothing is different on the moon beyond having a lower gravity and lots of vacuum. The only things that would affect k would be temperature, work hardening or being pulled out too far, past its linear stress-strain point.
