Yes and no.

They both have bash, however, not all commands are the same between OS X and Linux, and when the commands are the same, not all the options are the same. But for the most part command options available on OS X will be a subset of the richer set of options on Linux. There will only be a few commands on Linux that do not accept options available on OS X.
Configure /.bashrc or /.bashprofile to display colorful ls command. When bash is your login shell, it looks for /.bashprofile, /.bashlogin, and /.profile file in that order. When an interactive shell that is not a login shell is started, Bash reads and executes commands from /.bashrc. Hence you must add commands to /.bashprofile. According to the manual page that ships with OS X. It looks for /.bashprofile, /.bashlogin, and /.profile, in that order, and reads and executes commands from the first one that exists and is readable.The -noprofile option may be used when the shell is started to inhibit this behavior. It should only read /.profile as a last resort if neither /.bashprofile nor /.bashlogin are. The CLI and Bash Scripting.
Also OS X's bash is version 3.2.57(1), where as Linux is going to have a bash with a 4.something version. 98% of bash behavior will be the same, but there are going to be a few edge conditions where they may behave differently.
NOTE: Commands are separate from bash. Each is their own program and are not tied to each other in anyway.
I live in an OS X, Linux, Solaris, AIX Unix world, and for the most part I can write scripts on one platform and run them on any of the others. Where I have difficulties, I add code along the lines of
UNAME=$(uname)
if [[ $UNAME = 'Linux' ]]; then
.. Linux specific
elif [[ $UNAME = Darwin ]]; then
.. OS X specific
elif [[ $UNAME = AIX ]]; then
.. AIX specific
else U spin slot machine odds.
.. generic .. King neptunes mobile casino.

The reason OS X has an older version of bash, and why OS X does not include the Linux commands with all the extra options is that many of those programs have a GPL V3 license that explicitly excludes commercial Unix vendors from including them in their operating system distributions, so the commercial Unix companies are stuck with either GPL V2 licensed code, or code they got from BSD distributions, such as FreeBSD (a lot of OS X command are originally from FreeBSD).

I actually build and install my own current version of bash on my OS X systems. The GPL V3 license does not restrict you, only Apple.
There are several package managers that make adding open source commands fairly easy. Homebrew, MacPorts, Fink.
