Yes, of course!
How about \section[reference][number=no]{Whatever}?

The following is a bit verbose. It is related, but is more general than the 
subject of unnumbered sections...

I have to say that I am now a bit confused about the use of arguments in 
ConTeXt.

In LaTeX, optional arguments are contained within [] and required arguments 
are grouped within {}. However, in ConTeXt, the situation is not quite so 
clear. Take \section[reference]{Title} for example. Here, the reference is 
optional and the Title is required, so a title-less section would be 
\section{}. This is somewhat sane, even though one may well use sections 
without titles.

Contrast this with \cite (I choose this example as I just figured-out that its 
misuse was the cause of some obscure problems in a big project). We have 
\cite[key], rather then \cite{key} as in LaTeX. Is this because we may also 
have \cite[authoryear][key]? Of course, the key is not optional as one can 
hardly imagine using \cite without some sort of key, so one might expect 
usage: "as remarked by \cite[authoryear]{Einstein1905}."

My error was to have reflexively used \cite{key}, and this sort-of worked so I 
did not pay it any attention. However, here and there in my document, 
references, for example \chapter[ImportantStuff]{Important stuff} were broken, 
with no obvious reason. After correcting my use of \cite[key], other 
references were suddenly fixed.
