Without the need to "manually" step over the zeroth element (i.e., process only hash refs. that have a  'name' key): 

<c>
c:\@Work\Perl>perl -wMstrict -le
"use Data::Dump qw(dd);
 ;;
 my $data = [
   { val => 'action',  acc => 'Accounts',  id => 'None', },
   { name => 'PA1',  id => 'AUTOB' },
   { name => undef,  id => 'AUTOP' },
   { name =>   '0',  id => 'BOP'   },
   { name =>     0,  id => 'DFIRE' },
   { name =>    '',  id => 'HOME'  },
   { name => 'CM7',  id => 'CUMBR' },
   { name => 'BR1',  id => 'PUMBR' },
   { name => 'TY6',  id => 'ECUST' },
   ];
 ;;
 my $k = 'name';
 my $names = [
   map { exists $_->{$k} ? { $k => $_->{$k} } : () } @$data
   ];
 dd $names;
"
[
  { name => "PA1" },
  { name => undef },
  { name => 0 },
  { name => 0 },
  { name => "" },
  { name => "CM7" },
  { name => "BR1" },
  { name => "TY6" },
]

Update: Changed example code to include various false values for  $k selected key.
