I assume the euro stuff is all compatible because biodiesel is more common there and they have different emissions standards. Material wise, you just need synthetic rubbers, which have been standard since the 90's. The tuning issue comes from biodiesel being slightly more viscous. This effects injector diameter and injector pump pressure. The ignition point is also slightly different and timing can be adjusted, but I've never bother. Older diesels had enough tolerance that these things never mattered much, but newer ones aren't rated for more then 20% and I haven't heard of someone who's actually tested that.

It's also less relevant as HVO based diesel also comes from veg oil and is much, much closer to regular diesel then biodiesel is.
