No. I've a feeling they'l read but won't clear. (or is it the other way around?), anyway it won't be fully compatible that's for sure. Should be able to tap into the sensors though for logging throttle, boost, calculated load etc.
I have one, and I'm glad I have it, not so much use for the rovers but surprisingly it was compatible with some of the older vauxhall diesels and has proved to be worth it's dough (though you need special software to decode the vauxhall faults, but it comes through the elm interface fine).
I'd get one, learn what you can do with it then put it on the shelf till a need arises.
