Haven't you asked almost the same question before?
\set Staff.xxx = xxx sets a property value in the current
Staff context. If there is no such context, LilyPond has to
create one to be able to do the setting. Two lines later, you
create a new Staff context.
You have to do the setting within the context you want to affect:
\score {
   <<
   \context ChordNames \chords{ a b c d }
   \context Staff \notes{
      \set Staff.minimumVerticalExtent = #'(-0 . 1)
      a'4 b' c' d' }
   >>
}

In recent development versions, you also have the following convenient
syntax:

\score {
   <<
   \context ChordNames \chords{ a b c d }
   \context Staff \notes \with { minimumVerticalExtent = #'(-0 . 1) }
     { a'4 b' c' d' }
   >>
}
