Indeed, the original paper describing this species compared the holotype jaw to Tapejara and Sinopterus, implicating its affinities to this clade (or at least a large amount of convergence). If Bakonydraco is a tapejarid, it represents the only Late Cretaceous record of Tapejaridae known to date (aside from the slightly older Caiuajara dobruskii).
Indeed, the original study on this species noted that its holotype jaw was compared to Tapejara and Sinopterus, suggesting a possible connection to this lineage (or at least considerable similarity resulting from convergence). If Bakonydraco is a tapejarid, it represents the only known Late Cretaceous record of Tapejaridae to date (excluding the slightly older Caiuajara dobruskii).
