Can I 301 redirect old URLs to staging URLs (ex. staging.newdomain.com) for testing?

[esiow2013]

I will temporarily remove a few pages from my old website and redirect them to a new domain but in staging domain. Once the redirection is successful, I will remove the redirection rules in my .htaccess and get the removed pages back to live.

Thanks in advance!

But what if I remove the 301 redirect rules in my .htaccess file right(a few minutes) after successfully checking the redirected URLs?

If the redirect to the testing site actually is temporary, this is one of the very few instances I would recommend using a 302 redirect.  This way, the engines will understand that you aren't making this a permanent move and will, hopefully soon, remove the redirect when the staging site goes live.
