You can use a macro to assemble the "compound argument"... and, because 
<<currentTiddler>> is a TiddlyWiki *variable*, you can apply text 
substitution inside the macro using $(currentTiddler)$, like this:

\define whereto()
$:/$(currentTiddler)$
\end

<$link to=<<whereto>>>●</$link>

Note that, in the macro, the "$:/" is literal text, while the 
$(currentTiddler)$ portion is the subtitution syntax.
