Yes.
It's called Bitcoin Cash.

Another one is Bitcoin Satoshi Vision.
I am not a BCash or Bitcoin Fork fan, but I kinda disagree with this assumption that these are fake bitcoins. Remember, when someone counterfeits Fiat currencies, they make an exact (or close) copy of the original Fiat currencies. (notes or coins)
These forked coins are not an exact copy of the original Bitcoin (BTC) ....they tweaked several aspects of it and they used a different token to differentiate it from the original.
The strategy with these tokens are to use the word "Bitcoin" in their token to confuse people, in the hope that they would buy the wrong coin. (Just a cheap marketing strategy, like telling people that you have a Sale of up to 80% off on all items and you only have 2 items at a 80% reduction on the price.)

You don't need to make an exact copy to have a fake something. The important part is trying to sell the product as the original.
Some altcoins are doing more of it and some are doing less. Like BTG isn't really trying to scam people by telling everyone it's the one and only.
Both BCH and BSV are. BCH by confusing people that there's bitcoin cash and bitcoin core and bitcoin cash is better

and BSV by trying to sell this whole "I am Satoshi and this is my Bitcoin" lie.
