...having intrigued myself, I got my own answer from research last night.
Historically, any positioning for the proprietary emergency call systems was generally obtained via GPRS (i.e. mobile phone mast triangulation) which very strongly implies that other telematics (positioning) data would have largely been collected (or interpreted) via that method. Removal of the manufacturer-supplied sim would inhibit that.
The much newer, now mandated EU emergency call system, "eCall" uses GPS (not surprisingly from Galileo) but is explicitly flagged as being unable to be used for tracking, since the supporting module is "dormant" until it is rendered active by crash-sensors (e.g. the airbags being deployed).

I haven't read any of the background, so I may be off down the wrong alley, but if the vehicle was well-destroyed, then it is far more likely that data already transmitted, and still retained centrally somewhere (i.e. less transient than that held in the vehicle), would have been the source of info.
