Boot Into Recovery Partition After Installing Linux
Short answer:
It will be possible.

More elaborate answer:
If you leave the Recovery HD intact, you can still boot from it later on as the boot process Linux uses (usually GRUB these days) will not touch the ability to use the Alt key to boot from any attached bootable partition.

So, pressing Alt at computer startup will then present you with two options:


Windows (even though Linux is installed; some distributions may show their name though)
Recovery HD-&lt;version&gt; (&lt;version&gt; is the version of OS X at the time you installed OS X, which created the Recovery partition)


Additional:
You have a MacBook Pro (Mid 2014).  So, you can always reinstall the original version of OS X (which may be either OS X 10.9 Mavericks or OS X 10.10 Yosemite), which came with your computer as you can use the Internet Recovery even if your internal Recovery HD is gone entirely.

To start the recovery process, hold down Cmd+R at computer startup.  If a Recovery HD is found, it will be used.  Otherwise, the Internet Recovery is used.  To specifically force the Internet Recovery, hold down Cmd+Alt+R at computer startup until you see a spinning (or blinking) globe.
