I don't think so. Can you explain in what way it is invalid?
The From header in question was:
From: "=?ISO-8859-1?Q?Gjermund S=8F8rseth?="
<gjermund(_at_)nextra(_dot_)com>
The character "8F" is not printable in the charset iso-8859-1 your
header advertises. As pointed below, I suppose what you mean is
From: "=?ISO-8859-1?Q?Gjermund S=F8rseth?="
<gjermund(_at_)nextra(_dot_)com>
(without the first "8"), which decodes to
From "Gjermund Sørseth" <gjermund(_at_)nextra(_dot_)com>

Besides the topic of procmail, but anyway, according to an RFC (don't

mime.

RFC 822 forbids sending messages with non-ASCII characters in
headers. That's why those characters have to be encoded as either
Base64 or Quoted-Printable, as documented in RFC 2047.

RFC 2047 definitely allows (and defines) it. If Gjermund had
"S=F8rseth" (no "8" between "=" and "F") in his header, that would
be okay and would have to be read as "S", character F8 hex (in
ISO-8859-1) = o with slash, "r", "s", "e", "t", "h", but this way it's
"S", character 8F hex, "8", "r" etc.; if I remember correctly, 8F is
undefined in ISO-8859-1.
That's my point.

But I wouldn't worry too much as all widespread mailers (MUAs) seem
to understand that the From: line is mime encoded and decodes it
successfully.
elm 2.5 PL2 (or earlier) does not:
O 8 Feb 23 * =?ISO-8859-1?Q?Gje (64) Re: Envelope address in procmail?
Neither does my favorite mail pager ("less"). :-)
Last time I checked, elm was pretty "widespread".
Oh, Elm can decode those headers just fine, provided they are
syntactically valid, and you compiled it with the right options. I
can't be bothered to check right now, but IIRC version 2.5 can even
re-encode characters from one charset to another, allowing you to see
f.i. =?ISO-8859-2?Q?=BA= (latin-2 "s cedilla") as "s" if your charset
has encoding iso-8859-1.
