You can risk out but for sure it is written into their TOS but since you do already have the experience and prove it out then its safe to presume that it is still possible to do so but always mind off the risk
I checked Binance's TOS multiple times and there's nothing mentioned about restricted transactions coming from other services so it should be fine.
The only issue is that in the future they could make some changes in the TOS and include those restrictions.
i not really really recommend non custodial specially if funds been holding is for long term too.
Why not ? non custodial is better because you have control over your wallet.
