Yes, you can, but your movement over the ground will still be effected by the wind or no wind. You can slip without a thought to what's on the ground, but if you are aligning with a line on the ground, such as a runway, you have to have a thought about what's on the ground when you slip. Your control inputs cause the forward or sideward movement through the air, but your movement over the ground helps us understand that movement through the air.
You sideslip through a mass of air by applying aileron first, then enough opposite rudder to prevent the nose from following the lowered wing. If the air mass is not moving, the airplane will slip sideways over the ground to re-align with another ground reference, such as another runway. If there is wind, or a movement of the air mass you are slipping sideways through at, say, 10kts, and you effect a sideways movement through the air mass in the opposite direction at 10kts, you are staying laterally over the same place and looking straight out in front out the front window. With left aileron and right rudder.
If you are high and there is no wind and you apply rudder to off-set the nose, either way, and apply enough aileron to prevent the airplane fuselage from drifting away from centerline, and now you are looking out the left or right window at your ground reference point is not exactly choosing which window you look out as a 'difference'. It does point to one of the differences in the pilot's viewpoint diring either side or forward slip, but is not really all there is, since it matters about the wind.
If there is no wind and you are sideslipping, close to the ground, you would be looking out the side towards which you are slipping. If there is wind, and you are slipping to counter that wind, and you are close to the ground, you will be looking forward towards where the airplane is tracking.
