Thanks Hraban,

That should be fine, I've tried to increase the margins as well, but not
sure that's the issue as I can perfectly place text with \inmargin
directly, just not with the numbercommand.

MWE:

\starttext
\setuplayout[margin=2cm, leftmargin=2cm, rightmargin=2cm]

\showframe
\showlayout

\setupcaption[figure][location={rightmargin}]
\startplacefigure[title=Cow] \externalfigure[cow] \stopplacefigure

\define[1]\MyFormulaNumber{\inleftmargin{#1}}
\setupformula[numbercommand=\MyFormulaNumber]

\inleftmargin{Left Margin Text}
\inrightmargin{Right Margin Text}

\startplaceformula[reference=eq1] \startformula c^2 = a^2 + b^2
\stopformula \stopplaceformula
\stoptext
