Is it possible to control the position of a null object with expressions and a check box ?

What do you want to accomplish by doing this? Please elaborate on your actual intent.

So basically I have a checkbox that is controlling the opacity of one text layer already. When I turn the checkbox off to hide the layer of text I want the text under it (thats controlled by the null object) to move up.

Something like this? Alt+click the stopwatch for your text layer's Position property and paste the following:

if (thisComp.layer("CONTROL").effect("Checkbox Control")("Checkbox").value == true) value - [0,100] else value

You'll have to adjust the names "CONTROL" and "Checkbox Control" to match your setup, and you'll have to tweak that [0,100] value to match the number of pixels you'd like the text line to move.
