Yes, you can:

\documentclass[12pt]{book}
\renewcommand{\tiny}{\fontsize{7pt}{8pt}\selectfont}
\begin{document}
Normal size in 12pt. {\tiny This should be in 7pt}. And 12pt again.
\end{document}

See your log file ---book class uses bk12.clo; article, report and letter classes use size12.clo:

(/usr/local/texlive/2009/texmf-dist/tex/latex/base/book.cls
Document Class: book 2007/10/19 v1.4h Standard LaTeX document class
(/usr/local/texlive/2009/texmf-dist/tex/latex/base/bk12.clo
File: bk12.clo 2007/10/19 v1.4h Standard LaTeX file (size option)
)
