I've got a function which does roughly this. It has a number of issues
and, as I wrote it over eight years ago, I can't remember what those
issues are. I've attached it below. It works by removing characters
from the PREFIX and trying completion. It is intended to be used as a
completion widget via _generic:
zle -C retract complete-word _generic
zstyle ':completion:retract::::' completer _retract
bindkey '^[[24~' retract # F12
I'm not sure what the commented out line was for.

#autoload
local _comp_backup=1 bumax=30
if (( ! $+functions[compadd] )); then
compadd() {
local save oldp="$PREFIX"
SUFFIX=
# removing the -O option is a nasty way to make this work from _multi_parts
zparseopts -D -E O:=save
local i
for ((i=_comp_backup;i>0;i--)); do
PREFIX="${PREFIX%?}"
done
builtin compadd -S '' -F "( $oldp* )" "$@"
}
trap 'unfunction compadd' EXIT INT
fi
while [[ _comp_backup -le bumax ]]; do
_complete && return
(( _comp_backup++ ))
done
#builtin compadd - ''
return 1
