We report the results of a search for the decay modes ${B}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}{\overline{D}}^{0}$ and ${B}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{\overline{D}}^{0}{\ensuremath{\pi}}^{+}$. The analysis is based on $140\text{ }\text{ }\mathrm{f}{\mathrm{b}}^{\ensuremath{-}1}$ of data accumulated by the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. No significant signals are observed and we determine the branching fraction upper limits $\mathcal{B}({B}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}{\overline{D}}^{0})<2.0\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$ and $\mathcal{B}({B}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{\overline{D}}^{0}{\ensuremath{\pi}}^{+})<2.5\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$ at $90%$ confidence level. These results rule out the explanation of the excess in the low momentum region of the inclusive $J/\ensuremath{\psi}$ spectrum as intrinsic charm content in the $B$ meson. The branching fractions of the corresponding nonresonant decay channels are also reported.
