Is there a custom variable like ‘user-safe-local-variables’ which can be set to ‘(tab-width) to control this?

Looks there is only an `ignored-local-variables' user option. The
filtering is done in `hack-local-variables-filter' if you want to look
at the code. So it seems what you want is not possible by only
configuring an option, you would have to advice
`hack-local-variables-filter'.
Michael.

Thereʼs also 'before-hack-local-variables-hook', which you could use
to munge 'file-local-variables-alist' before it gets applied.
