Yes—this is most likely normal behavior from the lens’s Vibration Reduction (VR) mechanism, not the camera body itself. Even with VR switched off, when the lens first receives power it may briefly center the stabilizing element. That can cause a soft clunking sound and a slight visible shift in the viewfinder image. The same thing can happen when the camera wakes from standby, since the lens is powered again and the VR element may need to recenter. So the noise and small viewfinder movement are consistent with the VR system initializing.
