Is it possible to execute a group specific elisp block when entering a
group in Gnus?

There are several hooks that can be used according to your purpose.
Try `M-x apropos RET ^gnus-\(summary\|select\)-.*-hook$ RET'.

`gnus-select-group-hook' is run in the summary buffer just after
entering a group.  The summary buffer is empty.  You can refer to
the `gnus-newsgroup-name' for the news group name.  The variable
`gnus-article-buffer' holds the article buffer name but it has
not been created or has not been prepared.  For instance:

(add-hook 'gnus-select-group-hook
	  (lambda ()
	    (message "I just entered to the %s group"
		     gnus-newsgroup-name)
	    (sit-for 1)))

`gnus-select-article-hook' is run in the summary buffer whenever
an article has been displayed.  For instance:

(add-hook 'gnus-select-article-hook
	  (lambda ()
	    (message "This article has %d lines"
		     (with-current-buffer gnus-article-buffer
		       (count-lines (point-min) (point-max))))))
