Will it be possible to export the private certificate to terraform remote state

I am using two different aws accounts,
In account A - created a private CA, by using this private CA issued a private certificate. will it be possible to export the private certificate (certificate, certificate_chain and private_key) to terraform remote state.

In account B - created a instance which requires a certificate to perform one of its function.

will it be possible to reference certificate created in account A, to be used by the instance in account B.
