At the moment NCO.OP.111 applies, showing that LNAV/VNAV minima may only be used across EASA states if the VNAV profile is generated from Baro-vertical navigation, ie BaroFMS as alexbrett stated. EASA are aware of the anomaly wrt equipment capability vs regulatory permissions, but at the moment it's just not a major priority since all RNP Approaches were planned to include LPV minima. Sadly this hasn't always happened... Fortunately there aren't that many in the UK that are LNAV/VNAV but not LPV, with more recent approach approvals covering all possibilities.
