I'm a bit confused why you're not using \em in this situation, as it
adapts to both bold and roman contexts. If you dislike that it defaults
to slanted, then there's:

\setupbodyfontenvironment[default][em=italic]
{\bf Hello \em World} Hello \em World


But if you want to follow the path of defining your own, adaptive
switches, then you could look at these goodies already defined in font-ini:

%D \macros
%D   {emphbf,emphit,emphsl,emphtf}
%D
%D The next emphasis alternatives are for \THANH. They adapt
%D their style as good as possible.

\def\emphbf{\groupedcommand{\bf\def\emphit{\bi}\def\emphsl{\bs}}{}}
\def\emphit{\groupedcommand{\it\def\emphbf{\bi}\def\emphsl{\sl}}{}}
\def\emphsl{\groupedcommand{\sl\def\emphbf{\bs}\def\emphit{\it}}{}}
\def\emphtf{\groupedcommand{\tf\def\e
mphbf{\bf}\def\emphit{\it}\def\emphsl{\sl}}
{}}
