Yes, but there will be no UI for you to differentiate between BTC and B2X. And trying to spend one of them will result in spending the other unless specific precautions are taken.

I'm hoping that the Chainsplit service that Eric Lombrozo is working on will help us easily split our coins when the time comes, because using nLocktime (another method to split coins) in Electrum is not intuitive. Suffice to say that this is not a simple endeavor, and newbies who are in a hurry to spend their "free B2X" will definitely lose money. Be careful trying to interact with the B2X chain. Your best bet is to avoid making any transactions after the fork, and to wait for some trustworthy guides to emerge on how to safely split your coins.
