Manually upgrade 2.6.1 to 2.6.2

If only 12 files have been modified in 2.6.2 compared to 2.6.1, is it possible to simply manually replace ONLY these 12 files, and then run the upgrade PHP script? I mean the following files:

tags/2.6.2/wp-login.php (1 diff)
tags/2.6.2/wp-includes/post.php (3 diffs)
tags/2.6.2/wp-includes/version.php (1 diff)
tags/2.6.2/wp-includes/query.php (8 diffs)
tags/2.6.2/wp-includes/formatting.php (1 diff)
tags/2.6.2/wp-includes/pluggable.php (1 diff)
tags/2.6.2/wp-includes/widgets.php (1 diff)
tags/2.6.2/wp-settings.php (1 diff)
tags/2.6.2/wp-admin/includes/template.php (1 diff)
tags/2.6.2/wp-admin/includes/image.php (1 diff)
tags/2.6.2/wp-admin/import/textpattern.php (1 diff)
tags/2.6.2/wp-admin/css/press-this-ie.css (1 diff, 1 prop)
