MB 26: the fourth hour passed - even for a good reason, he still lost the blessings, and if one does make the blessings it is considered a blessing in vain, and see the Biur Halacha [where he writes that the Rambam says that one can say the blessings all the day. However most of the latter poskim go according to the Rosh, the Tur and the Shulchan Aruch. However the Biur Halacha comes to the conclusion that if one did not say the blessings because some accident prevented him from doing so, then he can say them until midday. (Note that saying the blessings until midday seems to be the common practice, despite the ruling of the Mishna Brura above. Consult your LOR.)]
MB 27: he can read - see the Levush who wrote that "he can read" means that it is proper to reads it, so as to accept the yoke of heaven. Nonetheless there is no requirement, since he is not fulfilling the commandment of reading the Shema as is agreed by most of the latter poskim, who say that the Torah commandment does not extend beyond the third hour. But one should realize that the parsha of tzitzit and other verses mentioning the Exodus from Egypt must be said at any point in the day, the Torah gives no time for fulfilling the commandment to mention the Exodus, as was written by the Sha'agat Aryeh, Siman 10, that until evening is the time for mentioning the exodus from Egypt, see there.
