From page 194 of Codex Space Marines:
Note that other Space Marine Chapters, such as the Blood Angels and the Space Wolves, deviate significantly in terms of organisation and fighting styles. These Chapters therefore cannot make use of any of the rules or abilities listed in this section, and instead have their own rules.
So no, Blood Angels can't use the stratagems and relics in Codex Space Marines. Codex Chaos Space Marines has similar wording for Thousand Sons and Death Guard.
