Why not try to ask this on Mistertango announcement thread from here https://bitcointalk.org/index.php?topic=1972805.240
The thread is not active but you can bump the thread and maybe someone knows if it is allowed to transfer EUR to transferwise from mistertango.
From personal experience, a friend tried to send funds from mistertango to my transferwise account, but he talked to support and they said they don't support those transactions (probably due to the competition). If you want an international balance, PayPal is probably the easiest way to do this, as long as you don't mind paying that much in fees. I'd recommend you to transfer the balance from mistertango to your own personal account, and then just send that via a simple transferwise transaction, or load up your account.
If you don't mind me asking, why didn't you just transfer the money directly via the exchange? Privacy, I'm guessing?
Paypal is horrible as an alternative, 2.5% FX fee sucks. Transferwise charges 0.5% and @OP may not have a SEPA account so he can't transfer the funds from Mistertango to his local bank account, hence using TW
@OP you can maybe use Uphold.com? I doubt they're 'anti-crypto' since there is Bitcoin as deposits option
