Not sure if I understand you right, but let's give it a try :-)
You can use 'Start|Stoppage' in combination with your icon, but you end
up with a graphic as big as the page (not visible and a small data
footprint, but still some kind of 'layer mess'). Probably not the best
way to do this in ConTeXt. Anyway...
StartPage;
draw <something> xyshifted(x,y); % shift to the desired position
StopPage;
Better alternative:

Example: placing a logo to the top right corner of the page
And for the different setup on left|right pages see
http://wiki.contextgarden.net/Alternating_backgrounds_and_repeating_layers
The latter link is also at the bottom of the layer related page.
