There is another possible attack vector by malware messing your dns or hosts file, so it might resolve electrum.org to a rogue phishing site. So no, not even that is safe enough (and actually searching it might give you the real IP address instead).
Another way to solve this is to use a live OS to access the website, download the files and verify it.
Installing anti-phishing malware might also help to prevent you accidentally access a punycode website, but of course, that won't work if your DNS was hijacked.
