Adding Schema and No index tags via GTM

[GregLB]

If we were to deploy schema and noindex tags to our website via Google tag manager, would these tags be viewed and respected by other search engines?

Take a look at this post on Moz - https://moz.com/blog/seo-changes-using-google-tag-manager. Also, take a look at https://productforums.google.com/forum/#!topic/tag-manager/Ilxks3tQKrg. Personally, I wouldn't recommend doing this via GTM. Noindex and Schema specially. They are both important for SEO and are better off done via the CMS.
