Hi Steffen,
the ConTeXt command to control the interword space is \setuptolerance,
the problem is there is by default (correct if I am wrong) no way to
choose a smaller interwordspace.
The low level TeX command to overwrite the default value provided by
the font ist "\spacefactor normalwidth plus stretchfactor minus
shrinkfactor". It is better include such commands only if you know what
you are doing.
I modified ConTeXts \setupinterlinespace to allow you to choose the
option "halfspace" with a narrower interlinespace than the default
value (I tested it oly with Latin Modern).
It could be a bad idea to change also the shrink and stretch values.
