You can set the forword string as labeltext and ignore the title (but 
use a empty argument when set userdata like the author).

\definehead
   [forword] [chapter]

\setuplabeltext
   [en]
   [forword=Forword,
    chapter=Chapter ]

\setuphead
   [forword]
   [frontpartlabel=forword,
    conversion=empty]

\setupsectionblock
   [frontpart]
   [number=yes]

\setuplist
   [forword]
   [label=forword,
    width=2cm]

\setuplist
   [chapter]
   [label=chapter,
    width=2cm]

\starttext

\startfrontmatter

\placelist [chapter,forword]

\startforword [] [author={A. u. thor}] \stopforword

\stopfrontmatter

\startbodymatter

\startchapter [title=Chapter 1] [author={A. u. thor}] \stopchapter

\stopbodymatter

\stoptext
