No, it's not legal to bypass the disc check software that you agree to adhere to in the EULA when installing the game.
Mounting the disc is making a backup of it, which is illegal in many countries, here's the Australian rules for example:
“Back-up” copies
There is no general provision allowing a purchaser of a computer game to make a “back-up” copy without the permission of the copyright owner.
The Copyright Act includes a special provision allowing purchasers of computer programs to make back-up copies, but this applies only to the computer program itself. Since computer games also involve other copyright material, such as films, music, sound recordings and artistic works, computer games cannot be copied under this provision.
If you wish to make a back-up copy of a computer game, you should check whether or not the licence allows you to. If there is nothing stated in the licence about backup copies, you will generally need permission from the copyright owner to make a backup copy.

Secondly to this, as mentioned above, it breaches the EULA (End User Licence Agreement) when you're installing the game, to bypass the CD check method that's in place. Mounting the disc in a program obviously bypasses this disc check method.
