Depends if you are asking can we or do we. As far as I am aware, there are no reasons prohibiting it assuming compliance with all the relevant laws and standards. However, equipment that is more sensitive to EM effects usually benefits from a greater separation. Also, the pantograph on the wire is noisy but some trains emit all sorts of "noise" and the maintainability of kit is made more complex by requiring de-energisation.
IRSE News actually showed an image from one country where signal heads were connected to the OHLE droppers. For maintenance, they were lowered by remote ground-level winches and no isolation was required (from memory).
Do we?; in the UK, generally no.
