Our answer to the question posed in the title is: probably no. In this work we show that it is rather unlikely that the structure $X(2265)$ reported by the DISTO collaboration corresponds to a kaonic nuclear bound state. The main argumentation is bas
ed on the repetition of the DISTO analysis on the HADES data sample, containing p+p reactions at 3.5 GeV. We further discuss many aspects in connection with the $pK^{+}Lambda$ final state and the $Lambda(1405)$-resonance. The results evidence possible problematics in the interpretation of the DISTO data.
