Of course, you can, I did that almost a year ago on the thread "Stake your bitcoin address" I signed message using ETH address instead of BTC because that time I haven't bought a PC yet. here it is.
I used ETH Address
0xc2c384240366b209c75ef9b730fe136ce1789f6f
{
"address": "0xc2c384240366b209c75ef9b730fe136ce1789f6f",
"msg": "yazher is the owner of this address, i hoped i will not be hacked.",
"sig": "0xd2934dc7bf5ba4493b7d62013bf6ce5514ba75c0859165f7b33e0d0278cdf18645455cd3619e1 45393a823c11ff728ca4ea257159ada0dda292746bd3fb1eb761c",
"version": "3",
"signer": "MEW"
}

Yes, it says Stake your
Bitcoin address but I think there is no thread for staking Ethereum address so I will still quote your signed message. Maybe we should start new thread for people who prefer signing messages with ETH address.
I also verified message:
https://etherscan.io/verifySig/1144 (There is space in the middle of your "sig" but I figured it shouldn't be there so after I deleted it, message got verified.)
