You could write [% list.join(', ') %]

You could also say:
[% FOREACH item = list %]
$item.NAME
[% ',' UNLESS loop.last %]
[% END %]
Or more verbose:
[% FOREACH item = list %]
$item.NAME
[% UNLESS loop.last %]
,
[% END %]
[% END %]
Or saving yourself from all that markup:
[%
FOREACH item = list;
item.NAME;
',' UNLESS loop.last;
END;
%]
