Hi Edward, Yes, test accounts cannot be linked to the MCC production accounts. However, in order to make calls to the AdWords API using your test accounts, you will still need to use the developer token associated to your MCC production account. You may then use the email address you used to create your test accounts to generate your OAuth2 credentials <https://developers.google.com/adwords/api/docs/guides/authentication>.
By using the OAuth2 credentials specific to your test account and your developer token, you will then be able to make calls to the AdWords API against your test account. You may also refer to our guide <https://developers.google.com/adwords/api/docs/guides/first-api-call> for more information about making calls to the AdWords API. I hope this helps and please let me know if you have any other concerns.
