If we take the center of earth to be the axis of rotation, then the moment of intertia of the two satellites will not be same.

As,

Moment of intertia = mr2

where,

m=mass

r=distace from the axis..

 

Since, their distance from the axis is different, their moment of intertia will also be different.
