You can slide it as far as you like in either direction, up to the point that the curved portion of the rail contacts the clamping surfaces. If you clamp part of the curve, you could damage the clamp and the rail.
Fore/aft saddle position is important to bike fit. If you're unsure of where to put it, you can Google the subject ("bike fit"), or start here:
