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).
In fact, the initial study describing this species compared its holotype jaw to Tapejara and Sinopterus, indicating its possible ties to this group (or at least considerable similarity resulting from convergence). If Bakonydraco is a tapejarid, it represents the only documented Late Cretaceous record of Tapejaridae known so far (with the exception of the slightly older Caiuajara dobruskii).
