Yes:
my $tt2 = Template->new();
# define a filter "foo" that wraps its input in <foo> tags
$tt2->context->define_filter( 'foo', sub { return "<foo>$_[0]</foo>"
});
my $template = qq{
[% "bar" | foo %]
};
$tt2->process(\$template);

Backreferences don't work with the TT2 replace filter. You could assign
the contents of $filename into a variable, and then get matches using
the match() scalar vmethod:
[% text = INCLUDE "${filename}" %]
[% matches = text.match('(?s)^([^\n]*)\s*(.*)') %]
<h2>[% matches.0 %]</h2>
[% matches.1 | html_para %]
