I think the number of spaces in a tab is set by the user, i.e. it's system dependent. Whether perl is able to change the system's setting, I don't know. But I'm left wondering why anything like that would be necessary when you can write one line of perl code to replace the tabs in a string with four spaces.
use strict;
use warnings;
use 5.010;
my $str = "Hello\tworld";
my $replacement = ' ' x 4;
$str =~ s/\t/$replacement/;
say '123456789012345';
say $str;
--output:--
123456789012345
Hello world
