You can place a texture on top of a shader, so yes you can. If you're doing a fence with glass I guess it depends on how you want it to look.
You could, for instance, place a glass shader on the surface then right click that surface and place a fence texture (with an alpha channel) on top of the glass shader, then enable the alpha channel to make the fence "see through". That's just one way to handle it.
You could also use 2 planes instead of one (one slightly in front of the other) and do a fence shader for one and glass for the other and set them exactly how you want them. This way you can add textures to either one of those shaders just for extra details, like adding vines or foliage to the fencing or putting a dirt map (make it mostly transparent) on the glass just for some extra detail.
There are probably several other ways you can accomplish what you are asking for.
