Everyone here in the previous comments are clueless, bitcoin cash and bitcoin use the exact same private keys so if you sent bitcoin cash to a bitcoin address the owner of that bitcoin address can claim it on a bitcoin cash wallet by loading up their private key.
In other words you lose nothing.
Yes absolutely we can,
BTC and BCH/BCC address are identically same,in other words they're living in the same roof.
even if you accidentally send it to your BTC address you still can claim it,
well another real history you can see it in here :
https://www.reddit.com/r/ledgerwallet/comments/6r48sm/accidentally_sent_btc_from_my_nano_s_to_a_bcc/he did it,and you can see it how he handled it.
obviously,if you send it into third party wallets you need them to help you out.
PS : For now you can do it,but for tomorrow ? try to avoid this kind of mistakes not a good thing for you to do it obviously.
That's why bcash has problems regarding send and receive, it has some bugs and must be solved.
I have read a warning before send bcc into btc address which said your bitcoin will be lost.
Well, I don't know for sure because I have not tried it yet but considering bcash and bitcoin running on different chain, it should be impossible to send one to another chain.
