\hyphenateurl{} works only when setupalign[] is set to hyphenated.
Is there a way to hyphenate only URLs?
You need to provide a few more options to \setupalign:
Why?

\appendtoks\tttf\to\everyhyphenatedurl % maybe we need a proper setup
Isn't that what \url is for? It has a setup command and uses
\hyphenatedurl.
sure, but it forces one to use \url which is not always an option (if 
there are thousands embedded in the text)
...
...
\setupalign[nothyphenated,stretch,tolerant]
This does not only change how URLs are typeset, but it also affects
the main text, which might not be desirable.
I got the impression that it concerned a whole document (we sometimes 
have that demand, but normally those have no urls anyway)

I don't see a single hyphenated URL in your result. The OP failing
to provide a minimal example, let me provide my interpretation of
the problem:
This is more visible

\appendtoks\tttf\to\everyhyphenatedurl
\lefthyphenmin=100 \righthyphenmin=100

maybe this is s better definition of nohyphens:


\unexpanded\def\nohyphens
   {\ifx\dohyphens\relax
      \unexpanded\edef\dohyphens
        {\lefthyphenmin\the\lefthyphenmin
         \righthyphenmin\the\righthyphenmin
         \relax}%
    \fi
    \lefthyphenmin\maxdimen
    \righthyphenmin\maxdimen}
...
\useurl
   [somelink]
   [http://bits.blogs.nytimes.com/2010/03/05/a-former-book-designer-says-good-riddance-to-print/?hpw&_r=0]
\setupalign
   [nothyphenated]
\starttext
   \url [somelink]
   \input knuth
\stoptext
I don't know how to start and stop hyphenation within a paragraph.
Allowing hyphenation for the entire paragraph is easy.
needs a bit it tinkering, maybe this is nicer:

\unprotect

\unexpanded\def\nohyphens
   {\ifx\dohyphens\relax
      \unexpanded\edef\dohyphens
        {\hyphenminoffset\the\hyphenminoffset\relax
         \lang_basics_synchronize_min_max}%
    \fi
    \hyphenminoffset\plusthousand
    \lang_basics_synchronize_min_max}

\protect

as it syncs nicely with languages too (characters carry left and right 
values so inline changes are possible)
