Unfortunately no (at least not by the built in functionality); custom tabs are not included in the Slide Properties 'Custom for the selected slides' window.
However.... IF (and you will notice that is a big IF) you are publishing your SL2 using HTML 5... you can use the following to hide the button. Note that this is for SL2 only; the identifiers changed with SL3/360 as noted in my original post.
- Find the button/tab and rename it. You can do this on your first slide at timeline start using the following JavaScript:
$(".customlink").attr("id","printButton");
- To hide the button/tab, use the following JS:
$("#printButton").hide();
- To show the button/tab, use this JS:
$("#printButton").show();
Note, this will only work in the HTML5 output of SL2.
