You can use DeleteSiteCollection extension method to remove the site collection.

It can be used as below:

string userName = "admin@tenant.onmicrosoft.com";
string password = "password";

string siteUrl = "https://tenant-admin.sharepoint.com/";

using (ClientContext clientContext = new ClientContext(siteUrl))
{
    SecureString securePassword = new SecureString();
    foreach (char c in password.ToCharArray())
    {
        securePassword.AppendChar(c);
    }

    clientContext.AuthenticationMode = ClientAuthenticationMode.Default;
    clientContext.Credentials = new SharePointOnlineCredentials(userName, securePassword);

    var tenant = new Tenant(clientContext);

    // use false, if you want to keep site collection in recycle bin
    tenant.DeleteSiteCollection("https://tenant.sharepoint.com/sites/Test", true);

}
