It’s a historical distinction. Bundeskanzler is the title of the chancellor of the Bundesrepublik Deuschland (Federal Republic of Germany), which has existed since 1949. Otto von Bismarck was the German Reichskanzler, i.e. chancellor of das Deutsche Reich (German Empire). The title of Reichskanzler was used until 1945.
