Yes, but v1.0 has vulnerabilities, which is why it's suggested to not use them. In fact, they're disallowed/blocked by some services, especially payment gateways, as they are not PCI compliant (as of June/2018). I know Braintree blocks the requests using v1/1.1. Some browsers will also block sites using TLSv1. Other services are blocking it too, and growing all of the time.
So, if you do, just realize you may be putting your site at risk.

You can google "TLSv1.0 vulnerability" for more info. I wouldn't use it.
