Short answer: no; or: it depends what you mean by 'separate'.

To paraphrase the example in the docs:

     1  #!/usr/local/bin/perl
     2
     3  use strict;
     4  use warnings;
     5  use HTML::Template;
     6
     7  my @array = <DATA>;
     8  my $template = HTML::Template->new( arrayref => \@array );
     9
    10  $template->param(loop => [
    11      { name => 'Bobby',
    12        list => [
    13            { list_name => 'the big bad wolf' },
    14            { list_name => 'He-Man' },
    15        ],
    16      },
    17    ],
    18  );
    19  my $stuff = $template->output;
    20  print $stuff;
    21
    22
    23  __DATA__
    24  <tmpl_loop loop>
    25
    26    <tmpl_var name>
    27
    28    <tmpl_loop list>
    29
    30      <tmpl_var list_name>
    31
    32    </tmpl_loop>
    33
    34  </tmpl_loop>


However, you could have a separate array whose reference you use
in the param() call, e.g.,


     1  #!/usr/local/bin/perl
     2
     3  use strict;
     4  use warnings;
     5  use HTML::Template;
     6
     7  my @array = <DATA>;
     8  my $template = HTML::Template->new( arrayref => \@array );
     9  my @list = (
    10      { list_name => 'the big bad wolf' },
    11      { list_name => 'He-Man' },
    12  );
    13
    14  $template->param(loop => [
    15      { name => 'Bobby',
    16        list => \@list,
    17      },
    18    ],
    19  );
    20  my $stuff = $template->output;
    21  print $stuff;
    22
    23
    24  __DATA__
    25  <tmpl_loop loop>
    26
    27    <tmpl_var name>
    28
    29    <tmpl_loop list>
    30
    31      <tmpl_var list_name>
    32
    33    </tmpl_loop>
    34
    35  </tmpl_loop>
