No company does, atleast not officially, however the effort to prove it is high and they dont want to loose customers, so they often give an rma anyway and as you can see on xs many customers exploit that to the full extent.

It's fairly difficult to kill a chip with overclocking (at least it used to be until recently), and we're such a miniscule market, that intel doesn't really care about allocating its RMA funds to a handful of xs members who want to abuse it. It's better than having the negative PR of unhappy customers. A lot of xs members have a bit of an influence, too.
and intel likes when we lap or use extreme cooling since it changes the appearance too, they also like that we now shun AMD when for all intensive purposes if u cant OC they are better for the price (flame suit). in all they just want a dead/almost EOL line to be kept alive so no1 starts complaining when there are no more large cash chips in 6 months
there also may be heat problems with the voltages in the i7 so they dont want u overheating it with bad temp monitoring

Tjmax is used to calculate the actual temperature from the DTS, it is an offset from a 7-bit word from Tjmax. This is accurate for mobile Core Duo and Core 2 Duo chips, since they are designed without an IHS and the Tjmax is specified for those die...
People assumed, since they are the same architecture, same die, that the mobile Tjmax is the same for desktop chips... this may or may not be true. So it will be nice to have the official Tjmax in hand to allow temp sensing programs to report accurate core temps without second guessing the calibration.
Here is a nice explanation of how thermal diodes work: http://www.maxim-ic.com/appnotes.cfm?an_pk=689.
Earn tons of cash?
Okay, surely something can't be right with the TjMax being 105*c for the 45nm E7200 - i've got ORTHOS fired up here at 4Ghz @ 1.4375v and it's reporting load temps of 86*c!!! This is with a Tuniq Tower 120, AS5 (Yes its properly seated) and the fans in my P182 on full - my laser thermometer reports the heatsink base at 38*c - what's going on?!
well when are we going to get it?
Awesome!
Now we can get some true temperature readings.
(Not sure why they didn't do this at launch though...)
*grumbles*
95? hang on, i thought it was 105*c?
I think its 100c for the 45nm processors.
intel already gave aways the Tjmax for the 45nm procs, so its no estimation ;) :

It was Tj, it was part of a intel presentation, maybe i can find it again.

It still doesn't sound right :/
Not doubting that - but my thermocouple and my laser thermometer don't lie...seems like a stupidly large temperature gap.
