Yes, but as you'll be breaking the fixed term before it's ended, you'll need to pay an interest charge.

We don't allow partial transfers, so if you choose to transfer out, you'll need to move the full amount in one go. This means, if you have Access ISA pots as well as Fixed Term ISA pots, you'll need to break the term on your Fixed Term ISA pots and pay an interest charge before transferring out — you can't just transfer your Access ISA pots.
