Your example works for me when I process it with mkiv but I would use a token list and not a macro to store the content.

\starttext

% macro

\def\foo{\startformula a = b \stopformula} \foo

\blank[2*line]

\edef\foo{\foo \startformula c = d \stopformula} \foo

\blank[2*line]

% token list

\newtoks\mytoks

\appendtoks
  \startformula a = b \stopformula
\to \mytoks

\the\mytoks

\blank[2*line]

\appendtoks
  \startformula c = d \stopformula
\to \mytoks

\the\mytoks

\stoptext
