Record somewhere (here: to the %found hash) what expressions have been found so far. At the end, check how many expressions have been found. Just counting the expressions isn't enough, as there can be 2 occurrences of expression 1, but no occurrence of expression 2.

#!/usr/bin/perl
use warnings;
use strict;
use feature qw{ say };

sub callForwardingsCF {
    my ($found) = @_;
    $found->{1} = 1 if /\t*CF=(CFU-TS10-ACT-(NONE|\d+))/;
    $found->{2} = 1 if /\t*CF=(CFB-TS10-ACT-(NONE|\d+))/
}

my %found;
while (<>) {
    if (/<SUBEND/)  {
        say "SUBEND found";
        if (2 == keys %found) {
            print "Both expressions found.\n";
        } elsif (keys %found) {
            print "Found only expression ", keys %found, ".\n";
        } else {
            print "None of the expressions found.\n";
        }
        %found = ();
    }
    callForwardingsCF(\%found);
}
