What is the maximum possible x position an object can have?
Is this also the maximum for all the other axis?

As far as i know the position of objects are stored as floats. Meaning that technically the maximum value for any of the axis is about ±1.5 * 10^45 to ±3.4 * 10^38 (http://msdn.microsoft.com/en-us/library/b1e65aza%28v=vs.71%29)
However because of the inaccuracy of floating points it is inadvisable to go above 5-6 digits numbers when dealing with 3D positions.
The Unity grid is 100.000 units, that is probably a good value to stay under. If you find yourself hitting this value you should rethink your implementation, and scale things down.
So short answer. Stay within -50.000 and 50.000 on all axis and you will be fine.
