A few options:
1) Write it as one plugin that installs both buttons, then you have
one shared code base and installation that you can reliably share the
code between.
2) Have two plugins that both import a library with the shared code
(but then you have two copies of the code installed)
3) Import the plugin A code from plugin B, checking first that the
file exists (i.e. the plugin A is installed)
4) Use QgisInterface to find the QAction that you installed for plugin
A and trigger that

Option 1 is probably best, option 3 probably the easiest from where you are now.
