Yes - no reason why not - It's just wire at the end of the day.
As I am sure you know the key is to make sure the replacement is the same physical length.
I seem to think with a bit of encouragement the receiver case will slip off and allow you to get to access the point where the wire can be unsoldered / resoldered.
If not a clean cut up one of the sides of the plastic case will allow it's removal and some tape will hold it back together.
